I was suggested to use sl pr unlink when trying to run sl pr submit when the associated GitHub PR had already been closed. I then attempted that, but it didn't seem to change the sl state at all.

This was on the macOS version installed by brew.

% sl version
Sapling 0.2.20240718-145624+f4e9df48
(see https://sapling-scm.com/ for more information)

This was the latest version available through brew (previously called brew upgrade sapling).

sl, sl pr unlink, sl (on the base commit bcc265a08):

% sl

sl pr submit still fails after this with the same error as before and offers the same guidance to use sl pr unlink.

I tried installing sl from brew at --HEAD, but that version is giving me issues:

% sl
