Add support for Linea-Sepolia and correct Goerli

[thedarkjester]

Added support for Linea-Sepolia - I think the format of the functions in the files changed - I don't have an auto linter on, so I am not entirely sure why it changed format.

All the changes are fixing Goerlia under Linea Goerli and adding Linea Sepolia support.

e.g.

 *  - Linea Goerli Testnet (``linea-goerli``)
 *  - Linea Sepolia Testnet (``linea-sepolia``)

and

registerEth("linea-sepolia", 59141, {});

and

        case "linea-sepolia":
           return "linea-sepolia.infura.io";

Merged in v6.12.0.

Thanks! :)
