No available formula with the name "pack"

[dentarg]

The README says:

To use the currently deployed heroku/ruby buildpack locally, you'll need a copy of pack installed. On a mac you can run:

$ brew install pack

but when I try this it fails:

$ brew info pack
Error: No available formula with the name "pack". Did you mean packr, spack, hpack, mpack, ack or pick?

$ brew -v
Homebrew 4.2.4
$ brew update
Already up-to-date.

@edmorley @schneems can you help out? how do I get pack?

For Pack install instructions, see:
https://buildpacks.io/docs/tools/pack/

@schneems Please can you fix the README (I suggest linking to https://buildpacks.io/docs/tools/pack/ instead of inlining the install steps, given there are other OSes, and also the current steps are wrong).

The docs were fixed in #263.
