Went through every test and fixed the output.
Took forever, but now that it's done it's done.

NOTE - built on top of #1821

This was called ts-ignore because it's testing only ts-ignores. That's why the other runs are ts-check, ts-nocheck etc

(Also no idea why I used backticks for these valids - I noticed this while doing invalid-void and facepalmed).
