Title: Replace /usr/bin/ruby with full Framework path

re: #12009, this commit replaces all usages of /usr/bin/ruby with the full Framework path, which is *hopefully* less likely to be altered.

Since we're no longer dealing with a default ruby path which is a symlink, I simplified the `brew --config` checks for the system ruby.
