What is the purpose of this pull request?

• [x] Bug fix

Description

Our naming guidelines were updated in #1874, but a lot of icons don't yet match the new official naming scheme, this PR updates most (if not all) of these icons, while also adding backward compatible aliases.

A renamePattern helper script was also created that helps streamline these batched renames, e.g. most of the hard work was done via running:

pnpm renamePattern "^([a-z-]+)-(square|circle|diamond|octagon|hexagon|triangle)$" "\2-\1"
