Find a way to do rebase from GitHub's UI

[Longwelwind]

This issue if more of a discussion.

Asking people to rebase their PRs is time-consuming. There are solutions listed there: isaacs/github#88. I don't what's the best.

I didn't go through all possible solutions but this seems to be easy and could be tested: isaacs/github#88 (comment)_

But it seems it only rebases on master. If it would respect the base branch of the PR it would be perfect.

Could not find a proper tool to do it.

GitHub Action doesn't allow to do that because PR from forks are not accessible with normal credentials, at least that's what I read from here: cirrus-actions/rebase#12.

Should be possible out of the box now.
