Build/Test Tools: Use newer versions for include jobs.

The `include` part of the strategy for the PHPUnit testing workflow defines a few testing configurations outside of the matrix. The versions of PHP and MySQL used in these have not been updated for some time. This was mostly due to various incompatibilities that have since been resolved.
