Suggestion

While working with ethers v6, given chainId 42 it's returning Kovan.
Kovan is now deprecated, and LUKSO Mainnet uses chainId 42. More info here: https://docs.lukso.tech/networks/mainnet/parameters

Keeping it this way will return inaccurate information to developers/users. (Example in a dApp ⬇️ )

I am happy to do the PR, if the change is approved.
