Improve types of hook source

[andrewiggins]

Improve the typing in hooks source file and add it to the jsconfig for linting on each PR.

One big change, that others may have opinions about, is that here I used unknown for types where we explicitly don't know what it is because it is user provided (e.g. the return type of the callback given to useMemo). Meaning, usages of any in hooks are places where we could improve the types, but I couldn't be bothered cuz it wasn't straightforward. Something to consider improving for later lol.

I wanted to to do this cuz I was recently looking at a compat bug in hooks and was working on a fix but refactoring things in hooks was slightly more difficult given I couldn't trust the red squiggles to be meaningful or not. After this PR they are hopefully more helpful (or at least mean you should double check this before adding an any override lol).

Nice, I'm all for stronger typing. Going with unknown is the right move imo 👍
