Unable to update gems without causing compile-test-assets as-if-jh to fail

I attempted to update Rugged in !73888 (closed), but this caused compile-test-assets as-if-jh to fail in https://gitlab.com/gitlab-org/gitlab/-/jobs/1755209981:

$ bundle install --jobs=$(nproc) --retry=3 --quiet  && bundle check
You have requested:
  rugged ~> 1.2
The bundle currently has rugged locked at 1.1.0.
Try running `bundle update rugged`
If you are updating multiple gems in your Gemfile at once,
try passing them all to `bundle update`
Uploading artifacts for failed job

!70000 (merged) was updated on October 25. Since then, Gemfile was only touched once or twice. However, https://gitlab.com/gitlab-org/gitlab/-/jobs/1752507493 passed fine.

I'm not sure why this is failing. The dd-jh-fodler job extracts the archive into the jh directory, and it looks like the Gemfile is pointing to to jh/Gemfile.
