Update fulu network configs and add MIN_EPOCHS_FOR_DATA_COLUMN_SIDECARS_REQUESTS (#7646)

- #6240
- Bring built-in network configs up to date with latest consensus-spec PeerDAS configs.
- Add `MIN_EPOCHS_FOR_DATA_COLUMN_SIDECARS_REQUESTS` and use it to determine data availability window after the Fulu fork.
