feat(eslint-plugin-react-hooks): convert to typescript and package type declarations

This change converts the eslint hooks plugin to typescript, which also allows us to include type declarations in the package, for those using [typescript eslint configs](https://eslint.org/blog/2025/01/eslint-v9.18.0-released/#stable-typescript-configuration-file-support).
