Download tap_migrations.json files from the API
Download the previously stored tap migrations files for homebrew/core
and homebrew/cask from the formulae.brew.sh API.

This adds a much longer stale time (24 hours) to decide whether or not
the migrations files need downloaded from the API in Ruby land.
`brew update` will still update them every time.

Requires https://github.com/Homebrew/brew/pull/15628
Fixes https://github.com/Homebrew/brew/issues/14897
