Turns out if :<something> is passed, a local branch is updated, which
can conflict if the PR branch starts with "pr". I tried to avoid that
with the original code but apparently that didn't work!

This makes this codeowner mechanism behave differently than the native
one, but there's no other way to avoid rerequesting reviews from teams
when a member already reviewed the PR.
The automation should never rerequest reviews from users that already
reviewed the changes, which is what was happening before this change:
https://github.com/NixOS/nixpkgs/pull/347354#event-14570645380
Also reorder the arguments to make more sense
Also post a comment in case base branch is wrong
This guides newcomers in how to smoothly handle the potentially scary
situation of having thousands of commits listed in a PR.
While CI shows the same, people might not even look at CI if the PR
looks botched.
