remove eslint-prettier-config

[anonrig]

Upon recommendation from @JoshuaKGoldberg (typescript-eslint/typescript-eslint#10635 (comment)), removing invalid typescript-eslint rule, and removing eslint-prettier-config because it takes too much time running eslint with prettier.

We already have a linter check using just f no need to do the same work twice.

PS: This decreases eslint test to 4.1s seconds from 8 on a 88 core machine.

LGTM, but the @eslint job is single-threaded so the number of cores doesn't really matter right?

Yes, I was just showing the ridiculousness of the amount of time it takes to lint and format our JS files...
