node: Add Celo bootnodes

[palango]

Taken from https://github.com/celo-org/celo-l2-node-docker-compose/blob/d369b3aa4457f8a2f49c7761169584ffd531ea17/envs/mainnet/op-node.env#L1C1-L2C1

Maybe we don't need to add all of them?

Resolves https://github.com/celo-org/celo-blockchain-planning/issues/883

Looks good to me, out of interest do you know how the bootnodes for other networks are handled by the discovery system?

I'm not sure. I assume that the handshake would be rejected, but I'll have a look.

IIRC, when decoding the ENR, there is a chain-specific field called opstack which is used to filter out bootnodes from other networks. (code)
