Subject: [PATCH] Updates for CustomDA config changes

This change supports config changes from
https://github.com/OffchainLabs/nitro/pull/3949

- Remove deprecated parent-chain-node-url and sequencer-inbox-address
  from node.data-availability (no longer valid for node config)
- Remove mode field from node.da config (DAConfig no longer has mode)
- Move parent-chain-node-url and sequencer-inbox-address in daserver
  configs (l2_das_committee.json, l2_das_mirror.json) from
  data-availability.* to parent-chain.{node-url,sequencer-inbox-address}
