fix: implementing the Hyperledger Identus SDJWT workshop

[elribonazo]

Description:

This PR not just brings the Workshop but the ability to build specific workshops easily in a single screen.

We can do so by defining each step with code examples and API calls and configure the interactive demo to do what we design it to do on each step.

• We must Add examples on how to start the agent and the mediator from windows, linux and mac.
• We must improve the examples in a clear way to it explicitly tells the users the files they need to create, etc
• We add a final step with the complete code.
• Improve UX of the Accept OOB buttons, show loading until the offer or presentation request is parsed and message emitted.
• Improve the UX for the Accept Credential Offer message, not showing loading button until the issued credential arrives.
• Improve the User experience, make all the buttons have the same size.
• Add more texts to clarify the missing steps that are empty. step === text + description
• Add github image from hyperledger into the header
• Configuring the mediator using its endpoint and show how to apply this in the code.
• Add pharmacy, patient and doctor issuance example
• Improve the user experience by grouping the API calls in blocks
• Improve code output formatting
