createVcTransaction return `Invalid arguments`

[samuraitruong]

Description

I add console logs into the createVcTransaction and confirm it has 3 params
2nd params is the string
3rd params as below

  _key: Ed25519PublicKey {
    _keyData: Uint8Array(32) [
      212,  37,  93, 181,   0, 126,  44,  56,
      105,  98,  51, 132, 136,  53, 125, 144,
      151, 184, 107,   3, 128,  23, 239,  91,
       72, 192, 150, 224, 202,  85, 241, 243
    ]
  }
}```

but the resolve of args[2] instanceof PublicKey -> false that why it come to the else statement




### Steps to reproduce

1. set up workspaces project using yarn
2. in the project add both dependency
.```
     "@hashgraph/did-sdk-js": "0.1.1",
    "@hashgraph/sdk": "2.6.0",

3. create Hedera helper on the main project with sdk 2.6.0
   const hederaHelper = HederaHelper.setOperator(
   hederaAccountId,
   hederaAccountKey,
   ).setAddressBook(null as any, null as any, topic);

Then later call hederaHelper.DID.createVcTransaction(vc, hederaAccountKey);

when hedera helper v2.6.0 create the call it using PublicKey refer on 2.6.0, but when inside the library there also has hedera 2.0.20 that make the validation become not valid

The workaround I can delete the sdk inside did after install or make the sdk version same with did sdk version.

I think it is good time to update the sdk to 2.6.0
