Move or copy pdtf-verified-claims.json schema to top level folder or inside latest schema version

[amolpednekar]

We use the verified claims schema pdtf-verified-claims.json to store to claims along with their verification.

This currently exists under src/schemas/v1, while our latest version of claims are under src/schemas/v3

I propose to either

• Copy pdtf-verified-claims.json and related tests to /v3 folder
• Create a folder under /schemas and move these files there (as they are not changing - when we move to verifiable credentials, it can have its own folder. This approach ensure we don't need to copy into every src/vN folder

Either option will avoid confusion for new-comers trying to understand the repository and schema structure of having to still look inside v1

Makes sense, good idea 👍 can you make sure the reference to verifiedClaimsSchema in index.js gets updated too?
