Transfer PR authorship

[jpraet]

Feature Description

It would be useful if the author of a PR could transfer the PR to another author.

It is not uncommon for PR's to be handed over to be completed by another developer.
When that happens, there are currently some problems:

• the new developer that is working on the PR can now approve his own work, this is not right
• the original author of the PR cannot approve / reject the PR, even though it's not really theirs anymore

It sounds a good feature but it is very difficult to make it completely right with some simple approaches, I can see a lot of edge cases.

IMO the clearest workflow should be "close the old one and let the new author start a new one".

If the head branch came from a fork repo, the new author may have no permission to push code

We close issues that need feedback from the author if there were no new comments for a month. 🍵
