Build/Test Tools: Run test coverage when PHPunit workflow changes.

[59287] updated the test coverage workflow to make use of the reusable PHPUnit workflow logic to prevent having duplicate code. The workflow should be run when the reusable file is updated to confirm any changes made work as expected.

See #62221.
