feat: credo as holder and jsonld issuance + verification

[GHkrishna]

What:

• Add Credo support instead of older AFJ
• Add JSONLD issuance and verification support

[anwalker293]

Hi @GHkrishna! We have a PR already approved (waiting on one change) to move from AFJ to credo as the holder. Could you just make this PR for jsonLD issuance and verification please? And can you please remove the Indicio-demonet files from everything? (The demonet for Indicio won't work / requires manual approval to anchor an endorser DID)

[GHkrishna]

Actually most of the testing for JSON-LD(issuance/verification) has been done with Credo and not AFJ, so will it be okay to keep the changes in the PR as is and only merge this PR when the credo as holder PR merges.

@GHkrishna Credo has been merged into owl-akrida

[GHkrishna]

Sure, had some minor changes, will sync

[GHkrishna]

I have updated the branch and made some changes, however I m facing some issues with schema interoperability between ACA-py and credo specifically for verification. Issuance works fine.
Not sure, if we can merge it until we figure that out or wait for its resolution, need your suggestion. I'll update the detailed error

@GHkrishna Could we have more information on what you're seeing? re: schemas

[GHkrishna]

In ACA-py, according to this resource the uri for schema in presentation request is https://w3id.org/citizenship#PermanentResident however in credo its only https://w3id.org/citizenship for this example. This causes issue with schema resolution on credo's side
