PHYSICAL DOWNLINK CONTROL CHANNEL MONITORING OCCASIONBASED CODEBOOK GENERATION ACCORDING TO VARYING CODEBOOK GENERATION CHARACTERISTICS CROSS REFERENCES [0001] The present Application for Patent claims priority to U.S. Provisional Patent Application No. 18/344,781 by Khoshnevisan et al., entitled ‘‘PHYSICAL DOWNLINK CONTROL CHANNEL MONITORING OCCASION-BASED CODEBOOK GENERATION ACCORDING TO VARYING CODEBOOK GENERATION CHARACTERISTICS,” filed June 29, 2023, which is assigned to the assignee hereof and which is expressly incorporated by reference herein. FIELD OF TECHNOLOGY [0002] The present disclosure relates to wireless communication, including physical downlink control channel monitoring occasion (PMO)-based codebook generation according to varying codebook generation characteristics. BACKGROUND [0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g.. time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA). frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). [0004] A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE). In some cases, a wireless communications system may support one or more wireless devices configured with feedback codebooks. SUMMARY [0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support physical downlink control channel (PDCCH) monitoring occasion (PMO)-based codebook generation according to varying codebook generation characteristics. For example, the described techniques provide for a user equipment (UE) to receive, in a first time slot, a downlink control information (DCI) message that indicates a second time slot for the UE to transmit feedback according to a codebook size. The UE may monitor a quantity of PMOs within a subset of time slots before the second time slot. The quantity of PMOs that the UE monitors may include a first set of one or more PMOs associated with a first codebook generation characteristic and a second set of one or more PMOs associated with a second codebook generation characteristic. The first codebook generation characteristic, the second codebook generation characteristic, or both may correspond to an index associated with a set of downlink control resources, a transmission priority, a type of communications, or some other type of characteristic. The UE may transmit the feedback via the second time slot according to a first codebook size based on the monitoring. The first codebook size may be based on a quantity of PMOs included in the first set of PMOs associated with the first codebook generation characteristics. [0006] A method for wireless communication at a UE is described. The method may include receiving, in a first time slot, a downlink control information (DCI) message indicating at least a second time slot for the UE to transmit feedback according to a codebook size, monitoring a set of multiple PMOs within at least a subset of a set of multiple time slots that occur before the second time slot, where the set of multiple PMOs includes a first set of one or more PMOs associated with at least a first codebook generation characteristic and a second set of one or more PMOs associated with at least a second codebook generation characteristic, and transmitting, via the second time slot, the feedback according to at least a first codebook size based on the monitoring, where the first codebook size is based on a quantity of PMOs included in the first set of one or more PMOs associated with the first codebook generation characteristic. [0007] An apparatus for wireless communication is described. The apparatus may include at least one memory and at least one processor coupled to the at least one memory'. The at least one processor may be configured to receive, in a first time slot, a DCI message indicating at least a second time slot for the UE to transmit feedback according to a codebook size, monitor a set of multiple PMOs within at least a subset of a set of multiple time slots that occur before the second time slot, where the set of multiple PMOs includes a first set of one or more PMOs associated wi th at least a first codebook generation characteristic and a seco
