Flank action on master is broken after #2616

[MRezaNasirloo]

Describe the bug
I’ve been using action/flank@master for a few years, and it started failing two days ago. It looks like this recent change (#2616) is the culprit.

After setting the version to the latest stable version (v23.10.1) it now works again

To Reproduce
