Subject: [PATCH] feat(explorer): adding verified on-chain collection support
 (#23490)

* Adding Verified On-chain Collection tag to help consumers check if their NFTs are authentic

* On-chain isn't quite the same as NO-chain

* Grammar fix

* Added Collection Owner verification to guarantee this is actually a Collection Mint
