Backport-action v3.0.2

Fixed

This release fixes a small bug in the draft_commit_conflicts option for the experimental conflict_resolution feature. When encountering conflicts, the backport pull request is opened in draft mode with the conflicts committed. Instructions are provided to resolve these conflicts locally, but these were incorrect. For more details see #421.

• Checkout draft branch instead of target in suggestion by @korthout in #423
