bug: messenger_sponsored_message in creatives is causing an error

[Ella6882]

The creatives stream is failing with the following error:

singer_sdk.exceptions.FatalAPIError: 400 Client Error: b'{"error":{"message":"(#100) Tried accessing nonexisting field (messenger_sponsored_message) on node type (AdCreative)","type":"OAuthException","code":100,"fbtrace_id":"AWM1NMF4RhxBraezjbe_ZNC"}}' (Reason: Bad Request) for path: /v19.0/act_777982726900652/adcreatives

We should exclude the field, messenger_sponsored_message, from streams > creative.py.
