Add blob_sidecar event to SSE (#4790)

Browse Source 
* Add `blob_sidecar` event to SSE.

* Return 202 if a block is published but failed blob validation when validation level is `Gossip`.

* Move `BlobSidecar` event to `process_gossip_blob` and add test.

* Emit `BlobSidecar` event when blobs are received over rpc.

* Improve test assertions on `SseBlobSidecar`s.

* Add quotes to blob index serialization in `SseBlobSidecar`
