Context

We use a generic JSON library for managing nested maps, github.com/Jeffail/gabs/v2.

This library only supports nested maps values of type any which bson.Unmarshall v1 output. After updating to go-driver v2 bson.Unmarshall now outputs any(go.mongodb.org/mongo-driver/v2/bson.D)

Definition of done

Being able to tell bson.Unmarshall to output map values of type any.

Pitfalls

There is probably a reason for the change, and I'd be interested to know what it is.

I tried using the decoder pattern, but it was the same result.
