chore: move plugins/ to separate repo, gitignore the directory

plugins/ is now tracked at bvandeusen/fabledscryer-plugins.
Removed tracked traefik files from this repo's index (files remain on disk).
Added plugins/ to .gitignore so the directory is ignored going forward.

PLUGIN_DIR in config.yaml still points to plugins/ for local dev and Docker.
