Add `brew tab`, a new command to edit tab information, as previously
discussed in https://github.com/Homebrew/brew/pull/17125#issuecomment-2068473483.
Currently, this supports marking or unmarking formulae as installed on
request.
Sample usage:
$ brew tab --installed-on-request curl
==> curl is now marked as installed on request.
$ brew autoremove --dry-run
[no output]
$ brew tab --no-installed-on-request curl
==> curl is now marked as not installed on request.
$ brew autoremove --dry-run
==> Would autoremove 2 unneeded formulae:
curl
rtmpdump
