Prettier linter throws exception on invalid yaml

[Aghassi]

If you use the prettier linter, it works fine with normal auto fixes, but if the yaml is invalid and prettier throws to stderr it causes the entire arc lint run to fail. I'll be looking into fixing this, but wanted to post here in case anyone comes looking.

EDIT: I noticed we extend a different base class internally, will follow up on if that is the root cause or not
