Prior to this PR, In the case where a `tf.diff.txt` is generated, but it contains no changes (e.g. only moves and imports), then the `grep` that looks for lines not starting with `^# ` would find no lines at all, causing `grep` to return a non-zero exit code, which causes the CI/CD workflow to fail. This PR fixes the issue by adding `|| true` to the relevant `grep`. The `true` command will output zero lines with a zero exit code, so it makes a good fallback here when the `grep` fails (because the `wc --lines` that follows will count zero lines).

This is fantastic, and the timing is superb! This has been plaguing TF-via-PR for a while so I'm grateful you took time out to contribute a fix -- thank you!

Thanks for fixing this! The "diff of 0 changes" cut is a little odd, but overall, it works, and fixes the issue we had in #433
