This helps in case you deleted a remote branch using the GitHub web UI,
so the local view is outdated.

# 1) You have 'gh' installed.
# 2) You are a committer, so you have the permission to push to a private/nick/name branch.
# 3) You delete this branch after the PR is merged.
# 4) "name" is the name of part of the private/user/name remote branch, defaults to the current
# branch. You have to specify this explicitly if you want to update an existing PR.
