Command fails on CODEOWNERS file with fewer than 100 lines

[khamusa]

If the CODEOWNERS file contains up to 99 lines, the following error occurs when running bundle exec code_owners -u:

bundler: failed to load command: code_owners (.../vendor/nix/gems/ruby/3.2.0/bin/code_owners)
.../vendor/nix/gems/ruby/3.2.0/gems/code_owners-2.0.1/lib/code_owners.rb:41:in `fetch': index 99 outside of array bounds: -99...99 (IndexError)

However, if I add one extra line, the error does not appear.
