Peer dependencies of eslint-config-react-app are outdated

Created by: lukyth

Is your proposal related to a problem?

Yes.

I got this warning when I install eslint-config-react-app

warning " > eslint-config-react-app@5.0.2" has incorrect peer dependency "eslint-plugin-flowtype@3.x".
warning " > eslint-config-react-app@5.0.2" has incorrect peer dependency "eslint-plugin-react-hooks@1.x".

Turns out eslint-plugin-react-hooks is already at 2.1.1 now, and eslint-plugin-flowtype is at 4.3.0.

Describe the solution you'd like

I can update eslint-plugin-react-hooks and eslint-plugin-flowtype to the latest version if it's a good idea.

Describe alternatives you've considered

Make those two a dependencies instead of peer dependencies (https://github.com/facebook/create-react-app/issues/6129).

Additional context

None.
