Fix: Handled IG unsupported file type (#5650)

We get 'unsupported_type' in the web-hook event only when Instagram faces issues processing the attachments. https://developers.facebook.com/docs/messenger-platform/instagram/features/webhook/ according to their document, we are handling the given types and are ignoring this one for now.

Fixes: #5428
