refactor(tazjin/emacs): refactor LRU workspace list to use ring.el r/6533

This built-in emacs library actually provides a data structure that
can work as an LRU list through the existing helper function to move
an element to the front of the ring if it already exists.

As a result, the code for workspace history moving becomes a lot less
brittle and complicated than it was before. No more carefully figuring
out when to modify state, just push it in the ring unless it's being
rotated already.
