Upgrade OpenSea API to V2. OpenSea published API V2 and is shutting down V1 (Testnet first)

[longbmk]

We are using OpenSea API V1 and OpenSea published V2. In Testnet, they shutdown V1 and we met this issue when buying the token. We need to upgrade to V2 soon before they closed V1 in production.

These are the TXs: https://sepolia.etherscan.io/tx/0xe4c28bb3f2e3e03e9aaaa11bcb094b14c9a13ac03eb68d6664764603d813b023
