Issuance templates creation

[matteo-cristino]

The From structure in the issuance template has wrong desription.

It should be something like Define here the attributes that will be present in the issued credential

Moreover since all the issuer template will end in the credential issuer well-know there should be a way to decide which language should be used. In this moment en-US is always used, like:

"questionnaire": {
  "format": "vc+sd-jwt",
  "cryptographic_binding_methods_supported": [
    "jwk",
    "did:dyne:sandbox.signroom"
  ],
  "credential_signing_alg_values_supported": [
    "ES256"
  ],
  "proof_types_supported": {
    "jwt": {
      "proof_signing_alg_values_supported": [
        "ES256"
      ]
    }
  },
  "display": [
    {
      "name": "Questionnaire kobotoolbox",
      "locale": "en-US",
      "logo": {
        "url": "https://play-lh.googleusercontent.com/eeGcGCSxVGVxET_oK0xGsn5vI_s42_9rwMx55Qrbu1e9r7XAxDdZLM5uSN-g47dk4cA",
        "alt_text": "Questionnaire kobotoolbox logo",
        "uri": "https://play-lh.googleusercontent.com/eeGcGCSxVGVxET_oK0xGsn5vI_s42_9rwMx55Qrbu1e9r7XAxDdZLM5uSN-g47dk4cA"
      },
      "background_color": "#12107c",
      "text_color": "#FFFFFF",
      "description": "This credential is issued after responding to a questionnaire on Kobotoolbox. The questionnaire is customizable, anonymous, the results can be later checked and the credential issued can be on a custom business logic. "
    }
  ],
  "vct": "questionnaire",
  "claims": {
    "formid": {
      "mandatory": true,
      "display": [
        {
          "locale": "en-US",
          "name": "formID"
        }
      ]
    },
    "instanceid": {
      "mandatory": true,
      "display": [
        {
          "locale": "en-US",
          "name": "instanceID"
        }
      ]
    },
    "submissiondate": {
      "mandatory": true,
      "display": [
        {
          "locale": "en-US",
          "name": "submissionDate"
        }
      ]
    }
  }

maybe also more than 1 language should be available for the same template
