Tap bundle and services in Codespaces

- Yes, I wanted to do more Homebrew stuff from Codespaces on my iPad
  because I couldn't be bothered to get out of bed and walk downstairs
  to get my laptop.
- For that I needed my `Homebrew/brew` branch and `brew services`
  tapped, with sufficient permissions for write access so I could
  push commits.
- So I thought I'd do `bundle` as well as it seemed like another
  "would maybe use Codespaces for this" tap.
