[sequencer] Blocks are being created with a future timestamp

[spalladino]

Found in the logs of the aztec-node when running the docker-compose.provernet.yml template:

aztec-provernet-aztec-node-1           | 2024-08-12T14:58:21.412Z aztec:sequencer [DEBUG] Not creating block because not enough time has passed since last block (last block at 1723474783 current time 1723474701)

Note that last block timestamp (which is defined by the same sequencer, as we have only one sequencer on this setup) is greater than the current time. We need to identify whether this is an anvil issue or a sequencer issue.

This is expected from #7758
