Cannot create comment on dependabot PR's

Whenever i merge a PR to my main branch, syncpack action will fail in the step where he tries to add a comment:

This makes sense to me, because in the moment he tries to add the comment, there is no pull request anymore, as it was just merged to main. Easy fix -> i disabled running syncpack on pushes to main.

But now, i get the same behavior in dependabot pull requests, where it should work i guess?

But now i think it is a bug that he cannot add his comment to the pull-request.

Start by inspecting how the syncpack GitHub Action handles comment creation for merged pushes and Dependabot pull requests. Reproduce the failure with a Dependabot pull request and verify that the action can add its comment without failing when the pull request remains open.
