Tag a previous Upstream Sync PR as duplicate of a new Sync PR

[jenstroeger]

would it make sense to check if a branch for that previous version exists, and close the PR and delete that now older branch? Or, if not, mark the older PR as a duplicate of the new PR?

The new branch that’s being opened should include all changes from that older branch🤔

Yes, the new PR should technically supersede the previous one and close it.
