registry: fix binary JSON content-type

Browse source 
This fixes registry endpoints to return the proper `application/json`
content-type for JSON content, also updating spec examples for that.

As per IETF specification and IANA registry [0], the `application/json`
type is a binary media, so the content-type label does not need any
text-charset selector. Additionally, the media type definition
explicitly states that it has no required nor optional parameters,
which makes the current registry headers non-compliant.
