Snowflake connection failure when only using the Airflow UI fields to set the connection

Hi!

I noticed that when only using the Airflow UI fields to set a connection the Extra JSON rendered has different keys than what the GXO is looking for.

Extra field automatically rendered from connection UI fields: {"account": "myacc", "warehouse": "HUMANS", "database": "DWH_DEV", "region": "us-east-1", "role": "myrole", "insecure_mode": false}

The GXO is looking for extra__snowflake__account, extra__snowflake__region etc. I think this might have been how keys used to be rendered? Setting the connection with these keys adding extra__snowflake__ in front of the parameters everything works as expected.
