Remove output compare GitHub Action (#6081)

This was nice when we were gradually migrating the codebase to
TypeScript so we could see if we changed a file from `.js` to `.ts` the
actual output remained the same, even when GitHub shows the entire diff
changed.

But now everything is TS and we aren't doing any JS to TS file changes
so we might as well remove this from CI.
