Inconsistency in documentation of Entry Endpoint HTTP responses?

[mromanello]

In the docs, the Entry Endpoint is the only one where it's not specified that the response headers should contain Content-Type: application/ld+json. Is this intentional?
Currently, the DTS-validator raises an exception if this is the case (albeit I do think that this should be turned into a warning, following the rationale: MUST -> exception, SHOULD -> warning).

An example of implementation not returning his key:value in responses of the EntryEndpoint is the DoTS demo: https://dots.chartes.psl.eu/demo/api/dts/

Good catch, @mromanello. We've fixed it.
