custom gas limit with -dev flag

[w-woloszyn]

Describe the bug

Running reth node with the dev flag and custom genesis.json seems to override the gas limit specified in genesis.json. I classify this as a bug, because other parameters set in genesis.json such as chain id or prefunded accounts are respected.

If this is not a bug, then I'd appreciate advice on how to set custom gas limit with dev flag.

Steps to reproduce

1. Start reth node with dev flag and custom chain specified in genesis.json with a gas limit different than 30000000.
2. Verify that the gas limit has not been set to the custom value, e.g. using eth_getBlockByNumber JSON-RPC method.
