Add Live Derivation path for Ledger

[0xclem]

Ledger derives ETH addresses from two different paths:

• Ledger Live: m/44'/60'/0'/0
• Chrome apps/ Mew: m/44'/60'/0'

Right now we're only using Chrome/MEW. Ledger Live derivation needs to be added. I've recently made the change into synthetix-js so the Ledger constructor is able to take a custom derivation path parameter.

const LEDGER_DERIVATION_PATH = "44'/60'/0'/";

class LedgerSigner extends Signer {
  constructor({ provider, chainId, addressIndex, derivationPath } = {}) {
    super();
     ...
    this.derivationPath = derivationPath || LEDGER_DERIVATION_PATH;
  }

So it is now possible to do something like:

const signer = new snxJSConnector.signers['Ledger']({derivationPath: 'xx/xx/xx'})

Here's the design which means to be implemented in the Wallet selection screen:

@bachstatter I would say this one is probably highest priority as we've got lots of users asking for it in Discord.

@bachstatter here's the copy (I don't think it needs translation).

I've tested minted and burning on both page one and page 2 with a trezor and it all seems to work fine!
