temporary repo my PR gets accepted? and then mkdocs material upgrades their pygments version.
while waiting on that, it's kinda weird: this lexer needs to be packaged in its own repo and then installed into the project you want it to be in. something with entry points... i dunno. See https://pygments.org/docs/plugins/, pygments/pygments#1603 (comment).
add this to a poetry project with poetry add -D git+https://github.com/t-mart/wowtoc.git.
