ethers: decrypt keystore examples

[nohkwak]

These examples shows how to use decryptKeystoreListSync function for keystore V3 and V4.

Thanks. But can you use the Wallet.fromEncryptedJsonSync instead? The decryptKeystore functions are too low-level for regular developers. The Wallet functions are the go-to options for decrypting a JSON keystore.

I updated examples to use Wallet.fromEncryptedJsonSync function.
But the example in case of multiple role-based key seems to be not working well.

1. Can you name the files keystorev3.js keystorev4_single.js keystorev4_multi.js?
2. Examples are not tests. Instead of comparing the results, you can just print account.address, account.privateKey please.

Yes, I updated.
