Python unit tests failing - latest sql image uses newer version that is not caught in regex

[crispin-ki]

Expected Behavior

Python unit tests pass (in test_sql_registry.py)

Current Behavior

Tests currently fail (both locally and in cicd such as here), as the mysql:latest image defined here now uses mysql Version 8.1.0, not 8.0.* as expected here

Steps to reproduce

Run one of the failing tests, such as pytest sdk/python/tests/unit/test_sql_registry.py::test_registry_cache[mysql_registry] -vvs locally

Possible Solution

A solution is to simply change this line from log_string_to_wait_for = "/usr/sbin/mysqld: ready for connections. Version: '8.0.*' socket: '/var/run/mysqld/mysqld.sock' port: 3306" to log_string_to_wait_for = "/usr/sbin/mysqld: ready for connections. Version: '(\d+(\.\d+){1,2})' socket: '/var/run/mysqld/mysqld.sock' port: 3306". I have tested this change locally, and tests then pass.

Changing the version to regex is more flexible, as if we change it just to '8.1.*' then we will run into this issues again. The regex will match any number of digits with either 1 or two dots separating them. This is what we want for version numbers.
