Issue description

MongoDB aggregation cursor return type cannot be modified

Expected Behavior

Aggregate method's generic parameter allows modifying the expected return type of the call.

Actual Behavior

The generic is redundant and the cursor will always hold the entity type instead of allow parameterization.
This is clear from the type signature.

Steps to reproduce

Attempt to perform an aggregation that returns anything other than the entities and observe the type mismatch.

My Environment

Additional Context

Happy to change the return type in the signature, but I need guidance on what the process is and whether I need to modify anything else.
