Moving the files into ../action was causing the job to fail because it couldn't find the test directory anymore. According to @adityasharad, these 'mv's should
not be necessary. Removing these means changing the path to the actions.

I'm also removing the 'config-file' input to keep the test minimal. I think this will mean that CodeQL will use the default query suite, so I hope that this doesn't change the results.
