Add campaign_ids to Facebook Business SDK for Ruby

Summary: Shopify is trying to send app events using Facebook Ruby SDK and it does not have the campaign_ids parameter. campaign_ids is listed as an optional field in [CAPI docs](https://developers.facebook.com/docs/marketing-api/conversions-api/parameters/app-data/). This diff adds campaign_ids to the Ruby SDK.
