Cleanup: Bring all the grammars up to a standard level of Lint compliance

[joshgoebel]

This is part of the larger task of auditing all the grammars for incorrect or exponential backtracking regex. To make those PRs simpler and easier to review we first clean them up with eslint --fix.

I've been against these type of sweeping changes in the past without good reason, but if we have to touch every single file anyways to clean up the regex (so it can be properly audited) then we may as well lint them first to make that job easier.

• A-F (chore) eslint --fix against most grammars #2853
• G, H, I
• J, K, L
• M, N, O
• P, Q, R
• S, T, U
• V, W, X
• Y, Z
