[BUG] MySQL master job cache doesn't work because mysql Python package is missing

Description
Upon upgrade to the latest salt master version (3007.1, installed via Debian Bookworm package from https://packages.broadcom.com/artifactory/saltproject-deb/ ), the salt master failed to start. We were using the mysql master job cache. In the master's log, I saw the error:
2025-04-24 16:14:05,473 [salt.utils.lazy :102 ][DEBUG ][1014420] Could not LazyLoad mysql.prep_jid: 'mysql' virtual returned False: No python mysql client installed.
2025-04-24 16:14:05,473 [salt.master :2355][ERROR ][1014420] Failed to allocate a jid. The requested returner 'mysql' could not be loaded.

I was able to fix it by installing the mysql module manually with pip:
/opt/saltstack/salt/bin/pip install mysql

This only worked after installing other packages with apt necessary for the mysql module to build:
apt-get install pkg-config python3-dev default-libmysqlclient-dev build-essential

This python module should be installed into /opt/saltstack by the package, right? Otherwise, further upgrades to the salt-master will blow it away again and undo my manual fix, I think.

Setup
(Please provide relevant configs and/or SLS files (be sure to remove sensitive info. There is no general set-up of Salt.)

This is an on-prem virtual machine in VMWare running Debian 12 bookworm. The onedir version of the salt-master package was installed from
https://packages.broadcom.com/artifactory/saltproject-deb/
using apt, e. g. apt install salt-master

Then the mysql job cache was configured by dropping a file called mysql_job_cache.conf into /etc/salt/master.d. Its contents are:
mysql.host: 'database_ip_address'
mysql.user: 'db_user'
mysql.pass: 'db_user_password_here'
mysql.port: 3306
master_job_cache: mysql

Steps to Reproduce the behavior
Install the salt master and attempt to configure the mysql master job cache, then restart the salt-master service.

Expected behavior
The master should start properly and send job results to the mysql database. After installing the python mysql package manually with pip in salt's onedir in /opt/saltstack as described above, this expected behavior works again.
