Subject of the issue

Summary: We are currently enforcing a requirement that any commit must be signed. When we create a pull request with this action does not currently create signed commits even if the source of the commits are signed off.

Steps to reproduce

We are manually triggering this action to create pull request to our branches test -> uat
All our commits to the base branch (test) are signed and merges to the base branch are created into releases/tagged.

We use this action to select the release we want to deploy.

Is there a way that the created PR will have commits that will be gpg signed, somewhat inheriting from the original commit?
