build(eslint-plugin-react-hooks): remove tsup

This change removes tsup from the devloop of `eslint-plugin-react-hooks`.  I was originally using it to quickly run tests and builds as I was doing the migration, but now that we've added support to the larger rollup build process, there's no longer a need for it.  I've added an index.js to the root of the package folder that's just a proxy for the `src/index.ts`.  It uses tsx to load it for other consumers in the monorepo (e.g. the eventual e2e tests fixtures).  For jest, the index.js is able to load the ts file due to the added configuration in the package's babel and jest configs.  This `index.js` will only be used for dev purposes.  The `index.js` that's in the `npm` folder is what will actually make it into the published package.
