ci: Update homebrew cask new dir (#536)

Issue #, if available:
Homebrew cask now partion its formulas by sub-folder, e.g., finch is
uder ./Cask/f/finch.rb instead of ./Cask/finch.rb
This is a regression from homebrew cask which breaks our homebrew
release automation.

*Description of changes:*
This pr updated the path in all places to unblock 0.8.0 release.

*Testing done:*
Will exercise the updated action after the PR checked in
