Support for Implementors draft https://openid.net/specs/openid-4-verifiable-credential-issuance-1_0.html (draft 15)

[jalauros]

Sphereon wallet in Apple Store does not seem to implement draft 15 which I believe to be OpenID implementers draft. Do you have plans to support it?

i.e. as I run the wallet the parameters sent to /credentials -endpoint seem not to follow that version of specification. It is not using parameters credential_identifier/credential_configuration_id but instead 'format' removed in draft 15.
