Replace mysql connector package in preparation of ansible mysql modules 4.x

[raypappa]

Ansible is deprecating use of this client, the new package would be python3-pymysql

ansible-role-mariadb/tasks/10_setup-Debian.yml

Line 5 in c2433c1

name: python3-mysqldb

I see this in my playbook runs

Warning: : Support of mysqlcline/MySQLdb connector is deprecated. We'll stop
testing against it in collection version 4.0.0 and remove the related code in
5.0.0. Use PyMySQL connector instead.

ansible-collections/community.mysql#654
ansible-collections/community.mysql#646

Given that 3.x has been out since 2021, I would say that 4.x is probably going to be soon-ish.
