Ensure highest supportd PHP/MySQL versions are used in local Docker Environment for all branches

[desrosj]

In #60095, the .env and docker-compose.yml files for the 6.2-5.8 branches were updated pin specific versions for LOCAL_PHP and LOCAL_DB_VERSION to ensure the local Docker environment continued to work as expected.

The tests never broke for branches < 5.8, but they all need to be updated to ensure the local Docker environment works correctly.

After reviewing, it seems that a few newer versions also do not have the right defaults in the docker-compose.yml files.

Renaming this ticket to so that this can be updated everywhere.

I've updated the ​section in the Core Handbook about Branching to be more clear about the values that need changing leading up to a release.
