Consider automatic releases

As mentioned in https://github.com/eslint-community/eslint-plugin-promise/pull/349#issuecomment-1256795963, this package isn't released automatically either, just like we have with [`eslint-plugin-eslint-plugin`](https://github.com/eslint-community/eslint-plugin-eslint-plugin) (see https://github.com/eslint-community/eslint-plugin-eslint-plugin/issues/301)
