<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Build/Test Tools: Introduce workflow for testing the local Docker environment.

While the PHPUnit workflow currently relies on the local Docker environment and provides some safety checks that the environment works as expected, this may not always be true and does not test all of the available commands related to the environment.

This introduces a basic workflow for testing the related scripts for the various supported combinations of PHP and database software with the environment to confirm everything is working as expected.

Ideally this would also be run on Windows and MacOS to catch platform specific bugs. Unfortunately, Docker is not supported within the GitHub Action runner images, so not all bugs will be caught by this workflow.

Props johnbillion, Clorith.
