feat: add Multikey support

[mirceanis]

What is being changed

This PR upgrades did-jwt, did-jwt-vc and @aviarytech/did-peer dependencies. The update fixes issues with did:peer identifiers that use multiple service endpoints as well as adding support for Multikey verification methods.

The updated libs also allowed the simplification of some codepaths that involved checking the key type and the fixing of some corner cases where the wrong key types were mistakenly used (like using secp256k1 for encryption).
