CLI creates payload is outdated key type

As of

  "name": "ion",
  "version": "1.0.3",

{
        "action": "replace",
        "document": {
          "publicKeys": [
            {
              "id": "signing-key",
              "type": "EcdsaSecp256k1VerificationKey2019",
              "publicKeyJwk": {
                "kty": "EC",
                "crv": "secp256k1",
                "x": "qp0Ezzc4YhA196COYKa-RHrCom-0LgFtAf8FqvcntN0",
                "y": "zWcbbbg9w1m-DNOszvM68TD0_vFBtWyc18S06c8cULU"
              }
            }
          ]
        }
      }

Should be

{
        "action": "replace",
        "document": {
          "publicKeys": [
            {
              "id": "signing-key",
              "type": "JsonWebKey2020",
              "publicKeyJwk": {
                "kty": "EC",
                "crv": "secp256k1",
                "x": "qp0Ezzc4YhA196COYKa-RHrCom-0LgFtAf8FqvcntN0",
                "y": "zWcbbbg9w1m-DNOszvM68TD0_vFBtWyc18S06c8cULU"
              }
            }
          ]
        }
      }

This is low priority, but will harm interoperability with JsonWebSignature2020, better not to encourage that key type to be used.
