feat: ✨ create `hypercert_claims` assets

[DistributedDoge]

This adds dbt model hypercert_claims and corresponding raw_ asset which lists Hypercerts created by Gitcoin grantees.

Thanks to this asset:

• We know creator, total_units, id of hypecert created by any grantee (on Optimism).
• uri points to IPFS hash with useful metadata like actual title or image of hypecert.
