Use compatible eslint-config-react-app and eslint-plugin-react-hooks. (#890)

This solves the following warning on yarn install:

`eslint-config-react-app@5.0.2" has incorrect peer dependency "eslint-plugin-react-hooks@1.x".`

`eslint-config-react-app@5.2.1` has widened its peerDep range to include `eslint-plugin-react-hooks@2`: https://github.com/facebook/create-react-app/blob/d2f813f8897ffcd2f0b0d2da75d0c44924c92f4d/packages/eslint-config-react-app/package.json#L26
