VC attesting when BN is optimistically synced
When we are only optimistically synced, we should not be attesting / producing blocks: https://github.com/ethereum/consensus-specs/blob/dev/sync/optimistic.md#validator-assignments
Here's a log from a time when the beacon node is synced but the underlying geth instance is still syncing:

We can see the corresponding attestation being published on the BN side as well.
