Convert `` to Python to workaround Bash array issues and for less duplication #7702

The current bash script violates Shellcheck for not properly quoting a variable. However, fixing this breaks the behavior and there is no simple way to fix it by converting the result of find to an array. See #7698 (comment).

This is not the first time the bash script has been difficult to work with. For example, #6747 took 26 commits to land and several back-and-forth code snippets over Slack.

Finally, the bash script has much duplication in it.


Rewrite to modern Python 3.


Bad imports will be caught the same as before.

To de-duplicate logic, the printed user message is a bit different, however. The failure message is also now outputted in red.
