A minor action which checks commits on a pull request for certain conformity policies. If all commits pass, the action succeeds and no comment emitted. If a check fails for one or many commits, the action fails and a comment is placed on the PR explaining which commits caused the failure and why. For instance, if contributed commits need to be signed off, a comment with this message will appear:
e3042c1: foobar
- check_signed_off: does not contain a valid Signed-off-by line
