Response examples should respect media-type

[mathis-m]

Description

Response examples do not respect the media type selected.
It just stringifies the json representation of the sample provided via examples or example keyword.
It should use the getSampleSchema method, which does take care of the content-type // media-type.

@mathis-m looks like linting errors that fail CI

[mathis-m]

@tim-lai gonna fix that in some hours

My approach is to override the response schema's example in case there is a matching media type example defined.
And use the new schema with the getSampleSchema util to generate a matching example.

still failing CI. this time in bugs/5458.js
