Deprecate Homebrew/homebrew-command-not-found

This doesn't seem to be used at all nowadays:
https://formulae.brew.sh/analytics/brew-command-run/365d/

As an official tap, it has overhead on e.g. RuboCop upgrades and a
presence in Homebrew/brew CI, manpage, etc. that no longer seems to be
warranted.
