Fix vendored_phpmd_path

[shanept]

Hi Greg,

This is the pull request that fixes #1 .

It is, for all intents and purposes an identical equivalent to my pull request for phpunit, with one exception.

There are 3 commits. In the second commit, I have changed the debug logging from the style you have been using (piping output to output.log) to the github actions debug output method. That means this output now shows up when a job is run in debug mode.

For reference, see here: https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#setting-a-debug-message

My preference would be for your error messages to move towards this method. If you aren't interested, let me know and I will remove the commit so you can merge.

Cheers

Hi @shanept,

Thank you for this. At the time of writing these actions, the output.log was the only way to achieve this (I was an early adopter of Github Actions, and there were plenty of missing features at the time!)

This is really useful, as debugging the output.log has always been a real chore. I'll try and find some time to implement this for the other repos.

Thanks again!
