Credential request format and types are not following the OID4VCI draft 12

[ntsbs]

The credential request in RFC001 3.9 Credential request is not adopting the credential request for jwt_vc_json in OID4VCI draft 12 Appendix E.1.1.5

The current version is using a types field which is not defined in the spec and it is using the wrong format identifier jwt_vc should be jwt_vc_json.

Current:

{
  "format": "jwt_vc",
  "proof": {
    "jwt": "eyJraWQiOiJkaWQ6a2...su7UFClz9NQnw",
    "proof_type": "jwt"
  },
  "types": [
    "VerifiableCredential",
    "VerifiableAttestation",
    "VerifiablePortableDocumentA1"
  ]
}

Expected:

{
   "format": "jwt_vc_json",
   "credential_definition": {
      "type": [
         "VerifiableCredential",
         "UniversityDegreeCredential"
      ],
      "credentialSubject": {
         "given_name": {},
         "family_name": {},
         "degree": {}
      }
   },
   "proof": {
      "proof_type": "jwt",
      "jwt":"eyJraWQiOiJkaWQ6ZXhhbXBsZTplYmZlYjFmNzEyZWJjNmYxYzI3NmUxMmVjMjEva2V5cy8
