[Idea] Create learning slides for full manifest flow

Create learning slides for a full credential manifest flow

Similar to this https://github.com/TBD54566975/ssi-service/blob/main/integration/steelthread_integration_test.go

But use different formats and proof types and see how they relate and what they do:

    "format": {
      "jwt": {
        "alg": ["EdDSA", "ES256K", "ES384"]
      },
      "jwt_vc": {
        "alg": ["ES256K", "ES384"]
      },
      "jwt_vp": {
        "alg": ["EdDSA", "ES256K"]
      },
      "ldp_vc": {
        "proof_type": [
          "JsonWebSignature2020",
          "Ed25519Signature2018",
          "EcdsaSecp256k1Signature2019",
          "RsaSignature2018"
         ]
       }
     }

Putting this here for now, while I craft a good place for it in the README VCs Demystified.pdf
