When I modify and save .arclint on my local machine, the file is linted by prettier as I have it installed.
These changes seem to be useful, so extending prettier to lint beyond the web/ folder would be nice. At any rate, this needs to happen because web/ is no longer a catch-all folder for javascript files in the monorepo.
This diff just lints .arclint. Will stack a diff to fix the target directories of prettier in .arclint
