Always run PHP-based github workflows (#2926)

Summary:
In PRs that don't modify any php files, the "Code sniff" and "PHP Unit Tests" checks get stuck in a pending state (ex. #2918). They do not run because the PR doesn't match any of the filters that the workflows define. This causes issues because our repository is set up to require all checks to pass before merging.

This PR updates the filtering on these workflows to run on every PR, regardless of what files were changed.
