Bump React Hooks ESLint plugin to 4.0.0

[gaearon]

Changelog: https://github.com/facebook/react/blob/master/packages/eslint-plugin-react-hooks/CHANGELOG.md

Note some of these will likely cause false positives:

• [ESLint] Extend isHook to recognize those under PascalCase's namespace react#18722
• [eslint-plugin-react-hooks] Disallow hooks in class components react#18341
• [ESLint] Forbid top-level use*() calls react#16455

People who get them will likely complain because it's really annoying. But we think the change itself is worth it and it's a bitter pill we need to swallow now rather than prolong it. The workaround, as always, is to disable-line the ones that are false positives and, ideally, rename them in code.

Thanks Dan!

@iansu, this would be good to reference in the release notes when we get to it to set expectations of the false positives.
