Type export change after 2.x.x update causes different import behavior

Hi!
First of all, thank you for your work on such an amazing plugin.

After updating the package from **1.14.0** to a **2.x.x** version, I noticed that the type definitions in the library have changed slightly, which now requires importing the package differently.

This happens because the current `export default` is just `ESLint.Plugin`, where configs is simply an indexed record. This differs from how other ESLint plugins usually handle their exports.

What do you think – would it be possible to restore the previous behavior?

P.S. The same issue occurs with `eslint-plugin-wc`, since (as far as I know) you’re the author of both 🙂
