Skip to an offset in a query.

        If the current query already has specified an offset, this will
        overwrite it.

        Args:
            num_to_skip (int): The number of results to skip at the beginning
                of query results. (Must be non-negative.)

        Returns:
            ~.firestore_v1beta1.query.Query: An offset query. Acts as a
            copy of the current query, modified with the newly added
            "offset" field.
