Update maintainers, manpage and completions.

[BrewTestBot]

Autogenerated by the update-manpage workflow.

There seems to be some issue with the workflow.

Two reasons combined:

• We should probably hard reset here to not revert other changes to the README like in
  ae82666:

  brew/.github/workflows/update-manpage.yml

  Line 43 in 68ae267

  git reset origin/master

• git-try-push does not do a git push --force-with-lease on the first attempt. So it actually does a git pull --rebase before force pushing and thus pulls back in the old commits.

I just opened a PR to change it to git reset --hard. Didn't know about the second issue, so I'll fix that as well in #10856.

Can this still be merged so manpages and completions are updated or does it need to wait for the workflow to be fixed?

Edit: nevermind...
