The GCStoGCS operator using the _replace=False_ flag and specifying _source_object != destination_object_, will not work properly, because it is comparing [apples](https://github.com/apache/airflow/blob/main/airflow/providers/google/cloud/transfers/gcs_to_gcs.py#L351) with [pears](https://github.com/apache/airflow/blob/0dd70de9492444d52e0afaadd7a510fc8a95369c/airflow/providers/google/cloud/transfers/gcs_to_gcs.py#L357).

Cause: the _prefix_ in the _pears_ case needs to be calculated from the _destination_object_, however, it is coming from the _source_object_.

:type delegate_to: str
    :param last_modified_time: When specified, the objects will be copied or moved,
        only if they were modified after last_modified_time.
        If tzinfo has not been set, UTC will be assumed.
    :type last_modified_time: datetime.datetime
    :param maximum_modified_time: When specified, the objects will be copied or moved,
        only if they were modified before maximum_modified_time.
        If tzinfo has not been set, UTC will be assumed.
    :type maximum_modified_time: datetime.datetime
    :param is_older_than: When specified, the objects will be copied if they are older
        than the specified time in seconds.
    :type is_older_than: int
    :param impersonation_chain: Optional service account to impersonate using short-term
        credentials, or chained list of accounts required to get the access_token
        of the last account in the list, which will be impersonated in the request.
        If set as a string, the account must grant the originating account
        the Service Account Token Creator IAM role.
        If set as a sequence, the identities from the list must grant
        Service Account Token Creator IAM role to the directly preceding identity, with first
        account from the list granting this role to the originating account (templated).
    :type impersonation_chain: Union[str, Sequence[str]]
    :Example:
    The following Operator would copy a single file named
    ``sales/sales-2017/january.avro`` in the ``data`` bucket to the file named
    ``copied_sales/2017/january-backup.avro`` in the ``data_backup`` bucket ::
        copy_single_file = GCSToGCSOperator(
            task_id='copy_single_file',
            source_bucket='data',
            source_objects=['sales/sales-2017/january.avro'],
            destination_bucket='data_backup',
