remove airbyte warning message

[pnadolny13]

Following MeltanoLabs/tap-airbyte-wrapper#15 the airbyte wrapper will attempt to pip install the python package if available before using docker. It seems that 260 airbyte sources are listed as pypi enabled so almost all of the ones we list on the hub will be python supported. For this reason we should remove the warning message. Maybe we should look into what sources arent pypi enabled and leave the warning for those few.
