Update detroit hard fork block height on mainnet (#253)

# Description

The PR determines and updates `detroit` hard fork block height on
`MainNet`. The new version should include this `mainnet-genesis.json` in
its archive file.

# Changes include

- [x] New feature (non-breaking change that adds functionality)
- [x] Breaking change (change that is not backwards-compatible and/or
changes current functionality)

# Breaking changes

From the height it sets, not updated node would not be able to sync with
the MainNet network.
