Seems it's because the action builds the branch first, and then builds the branch's base. However, when running git reset, the newly generated changelog entry file is not removed, but the authors list is re-generated. I think the fix is to read authors.json first and only append extra entries.

Okay, this works as well 😄

I believe it works but unfortunately, I can't verify this in current PR as it seems it executes the clean script of the main branch 😅

Will merge this assuming it works and open another PR to verify
