Add support for Verifiable Credentials Data Model v2.0

[parviz-mv]

VC Data Model v2.0 introduces new contexts:

"https://www.w3.org/ns/credentials/v2",
"https://www.w3.org/ns/credentials/examples/v2"

When I try to issue a credential with a new contexts:

const credential = {
  "@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://www.w3.org/ns/credentials/examples/v2",
  ],
  id: "https://example.com/credentials/1872",
  type: ["VerifiableCredential", "AlumniCredential"],
  issuer: "https://example.edu/issuers/565049",
  validFrom: date.toISOString(),
  validUntil: untildate.toISOString(),
  credentialSubject: {
    id: "did:example:ebfeb1f712ebc6f1c276e12ec21",
    alumniOf: "Example University",
  },
};
const verifiableCredential = await vc.issue({
  credential,
  suite,
  documentLoader,
});

I got an error:

Error: "https://www.w3.org/2018/credentials/v1" needs to be first in the list of contexts.

Also, if I use v1 contexts with a new validFrom and validUntil properties, credential successfully issued, but contains issuanceDate property which was renamed to validFrom in v2.0 spec:

{
  '@context': [
    'https://www.w3.org/2018/credentials/v1',
    'https://www.w3.org/2018/credentials/examples/v1'
  ],
  id: 'https://example.com/credentials/1872',
  type: [ 'VerifiableCredential', 'AlumniCredential' ],
  issuer: 'https://example.edu/issuers/565049',
  validFrom: '2023-08-11T10:07:34.116Z',
  validUntil: '2023-08-11T10:09:34.116Z',
  credentialSubject: {
    id: 'did:example:ebfeb1f712ebc6f1c276e12ec21',
    alumniOf: 'Example University'
  },
  issuanceDate: '2023-08-11T10:07:34Z',
  proof: {
    type: 'Ed25519Signature2020',
    created: '2023-08-11T10:07:34Z',
    verificationMethod: 'did:example:1234#z6MknsvN6TxRX8WQ3tC1MToBp9Wc6EX2jCYnVTnkNcXrDCg3',
    proofPurpose: 'assertionMethod',
    proofValue: 'z3m5SNbh5PGn7LYv2mZKLwNvyGKpV6mSytuDdWF4Xziv1pfkUNpiGFiRjTwRxX9kXR3LNshUnRM3tieBP3meqGAry'
  }
}

Hello @JSAssassin cc: @parviz-mv

1. any updates on this issue?
2. As you mentioned support for VC Data Model 2.0 is under development. Do you have any rough estimate of when it will be done/available?

@bparth24 @parviz-mv you may use the existing release candidate for VC 2.0 here: https://github.com/digitalbazaar/vc/pull/148

Also do note: the VC 2.0 context is changing relatively soon: https://github.com/digitalbazaar/credentials-v2-context/pull/10

The R.C. has been reviewed multiple times so I believe the major hold up at this point is continued changes in the VC 2.0 spec and also some changes in dependent libraries (we want the newer version of jsonld.js in the next release).

p.s. any feedback or review comments are welcome.
