Please address the brew style issues (i.e., some of these regexes are unnecessarily using the %r{} syntax now).

The modified regexes should also be updated to use ^ at the start and $ at the end. The existing regexes effectively anchored the start of the tag with /tag/ and the end with ["' >] and those can now be replaced with ^/$ (in keeping with Git strategy regexes).

Once that's done, I'll push a few commits that address the livecheck blocks that this doesn't fix.

So we don't hold this up, I'll take care of this in a follow-up PR since it wasn't addressed here.

We'll need someone else to approve this, since I pushed the most recent commit.
