cmd/{rb,nod}env-sync: add new commands.
Add these commands to ease use of Homebrew's bottles with `rbenv` and
`nodenv`.

I've had a lot of people request this over the years and it's worked
well for me for a long time.

I could see people extending these to support other languages or version
managers so perhaps we want a more generic name.

Create symlinks for Homebrew's installed Ruby versions in ~/.rbenv/versions.
Note that older version symlinks will also be created so e.g. Ruby 3.2.1 will
also be symlinked to 3.2.0.
