Ensure user-event folder is included into final bundle

[Yurickh]

What:

With the changes introduced in #24, there's a user-events folder inside the types folder that isn't being added to the final, published, library. This change ensures that this folder is also included.

Why:

Since there's a reference to the folder inside of types/pure.d.ts, the whole types for the userEvent library become any.

How:

By adding types/user-event/**/*.d.ts to the list of included files, we're ensuring the final bundle also includes the content of the types/user-event folder.
