Pagination and query TypeScript improvements #2564

The current TypeScript related improvements in v5 are pretty solid but the following improvements should still be included:

• Typed queries: This would allow to type params.query which will play well with the new schema types.
• Inferred pagination: The return value for a find is currently Paginated<T>|T[] which means you always have to cast the result. We should find a way to either set a fixed find return value or infer it from the paginate settings.
