fullProjectPath is not set when using runAsHostUser

[FlorianGlawogger]

Bug description

When setting runAsHostUser to true, the action gets the host user/group information using the stat -c command on "$fullProjectPath", however, this fullProjectPath variable is never set. This results in the following error message:

stat: cannot statx '': No such file or directory
Error: The process '/usr/bin/docker' failed with exit code 1

and then the action aborts.

How to reproduce

Start the unity-test-runner action on a self-hosted runner (running Ubuntu) with runAsHostUser set to true.

Expected behavior

I expect the action to run as host user (the full project path would need to be set) and not abort.

Additional details

The problem might also be a configuration problem on my side, but I believe the problem is in the entrypoint.sh file, above line 16. I think the line where the fullProjectPath is being set is missing. (or at least I compared to the entrypoint.sh of unity-builder, and there at line 14 the fullProjectPath variable is set, so I think this line is needed for the unity-test-runner as well.

fullProjectPath="$GITHUB_WORKSPACE/$PROJECT_PATH"

I hope I described the issue sufficiently, if not I'd be happy to provide more details. Thank you for your help!
