This PR adds two commands to l2geth:

- `geth init <url> <genesisHash>`, which will download a remote genesis JSON file, compare its hash to the one specified on the CLI, then reinitialize the chain config.
- `geth dump-chain-cfg`, which will dump the current chain config to stdout.

These commands will make it easier for us to adopt the upcoming gas schedule hardfork.

The logline `Blocknumber monotonicity violation`
was being logged erroneously. This commit ensures
that it is not logged when it doesn't need to be
logged.

It would previously log if the L1 blocknumber
was equal to or less than and now it only logs
if the L1 blocknumber is less than.

chore: add changeset for l2geth

Add missing changeset for https://github.com/ethereum-optimism/optimism/pull/2011

A replica can be configured with the flag
`--sequencer.clienthttp` or the env var
`SEQUENCER_CLIENT_HTTP` which points to the
sequencer and when users hit the RPC endpoint
`eth_sendRawTransaction` it will forward the
value to the sequencer.

If running a mainnet node, this value should be
set to `https://mainnet.optimism.io` or an
infrastructure provider such as Quiknode, Infura
or Alchemy.

feat: regenerate receipt json for optimism fields
