openlineage,gcs: use proper name for openlineage methods

[mobuchowski]

The GCSToGCSOperator uses wrong names for OpenLineage methods. Those should be get_openlineage_facets_on_complete.

BTW, maybe we should make it "official" interface in BaseOperator to prevent those mistakes.

Or create an interface (maybe multiple ones) to encapsulate all these methods, and add it as a super class for the operators/hooks classes.
In this case, you can replace method_exists("get_openlineage_facets_on_start") by isinstance(task, <interface>).

Agree (@hussein-awala 's comment). That would also make it easier to see if the operator already is "supposed" to have Open-Lineage integration
