What's this PR do?
this just updates to the latest version of our eslint configuration, which adds the react-hooks preset. this allows the linter to find a lot of issues where the logic of hooks is being violated - it found a bunch of callbacks which did not have their dependencies properly specified, for instance, which could lead to bugs related to stale data inside the closure of the callback.
How should this be manually tested?
there aren't really any code changes - the only things are renaming some things so that the linter knows they are hooks and turning off rules in a few, specific places. so I think just read through it and make sure things look good, and possibly do a quick smoke test of the app to make sure I didn't break anything.
