Currently it works like that:

• it is possible to select Tests (PHPUnit), but Github Actions aren't being checked on tests selection.
• while selecting Github Actions workflow, Tests (PHPUnit) got selected as well, but it is possible to unselect it manually and Github Actions workflow still stays selected.
• while selecting Github Actions custom workflow, Github Actions workflow and Tests (PHPUnit) got selected both (it seems that 2 Github Actions workflow files is redandant), also it is possible to manually unselect any of those as all checkboxes are always not disabled.

Correct

Actually thing to do is like we do with services. Eliminate the dependency requirement and instead include the GitHub actions file with the tests output so one always gets made when tests are selected.
