- This was done with `brew typecheck --update --suggest-typed` which
(as of the previous commit) uses Spoom, yet another gem. I thought I'd
see how well it works. There are no Sorbet errors after these changes!
- Add sponsors updating to the existing man/completion/maintainer update workflow
- Hide/deprecated --fail-if-not-changed arguments and make them default behaviour
- Rename man-completions workflow to sponsors-maintainers-man-completions for consistency
- Make output and exit codes more consistent between these updating commands
- Fix maintainers updates not always being committed correctly
