Missing implementations in Upstream

[AYaoZhan]

The current version of IdentityHub (0.14.0) we are using, has some missing implementations in the upstream.

• IssuerService CredentialsAdmin API <- this affects the endpoint /v1alpha/participants/{{PARTICIPANT_CONTEXT_ID}}/credentials/offer
• Presentation API <- this seems to affect when there is a presentationDefinition defined.

Maybe implemented in 0.15.0
