Subject: [PATCH] vim-patch:9.1.1906: filetype: not all Ruby files are
 recognized (#36526)

Problem:  filetype: not all Ruby files are recognized
Solution: Detect *.rbi and Brewfile as ruby filetype
          (botantony).

- `rbi` is a file extension used by Sorbet, typechecker for Ruby:
   https://sorbet.org/docs/rbi

- `Brewfile` is a bundler file for Homebrew package manager:
   https://docs.brew.sh/Brew-Bundle-and-Brewfile

closes: vim/vim#18697
