JWKS: Remove publicKeys in favor of RFC7515.

Fixes: #313

This is already good, do you think we could provide an example of how to use the jwks.json? Also, at this point I'm ok to keep the deprecated part, but I'd remove the now-fully-outdated example.

I removed the deprecated example now. Where would be a good place to put an example, and how would you like it to be? An example json with the various fields?

Good question: what about an Appendix as it was done with the previous example? Then yes I'd include an example JSON like the one in #313, and a code snippet from your own toy implementation (it's python IIRC right?) to 1) encode and add a signature at the sender and 2) validate it at the receiver.
