Display examples in other mime types than defaults

[sroucheray]

Today only examples provided with a mime type containing json | xml | text | jose are rendered. I think it is a bit limitative. I have examples with other mime type contents that could be displayed because they are plain text but their mime types are not whitelisted (e.g: application/n-triples). I see several solutions to the problem but I would like to know your point of view on the subject @mrin9 :

1 - add other mime types to the list, but it does not scale 2 - add a component attribute to specify other mime types that can be displayed as string, it seems very technical and we should be able to infer proper default without a user input 3 - add a component property which should be a function taking a mime type and a content an returning a formatted html string, this should be useful to render various mime types but maybe it is again too much technical 4 - remove the test on mime types altogether considering that if an example is provided it must be a literal so can be displayed in the browser https://spec.openapis.org/oas/v3.1.0#fixed-fields-15, but those tests are here so maybe they are useful https://github.com/rapi-doc/RapiDoc/blob/master/src/components/api-request.js#L775
