Checkout a PR branch without resetting anything

Discussed in #511

I would like to be able to checkout the already existing local branch corresponding to the PR at point in magit-status. Currently, b f (M-x forge-checkout-pullreq) also resets the branch and I don't want that.

Said differently, I would like the same as b b (M-x magit-checkout) but with a list of PRs (and the PR at point by default) instead of a list of branches.

Just for clarity, would this add a fourth option to

A branch named "my-fix" already exists.

⋮

  [r]eset existing "my-fix" branch
  [c]reate new "pr-1234" branch instead
  [a]bort

something like [u]se existing "my-fix" branch?

Because that is a feature I would love.

The PR I sent avoids this choice and directly checks out the existing branch.
