Stack equivalent of gh pr update-branch --rebase

[eelco]

We run CI tooling on top of the normal merge queue that makes sure PRs are rebased (to achieve semi-linear history, still waiting on that option 😉). The tooling works fully with gh to manage merging, rebasing, etc. without having to do a repo checkout.

As far as I can find, only gh stack merge <nr> can work without checkout. I’m looking for the equivalent of gh pr update-branch --rebase that also works with stacks, because as far as I can see all other stack methods need checkouts.
