Add request language to @context

[syphax-bouazzouni]

Requirement

If we call this endpoint https://data.stageportal.lirmm.fr/ontologies/INRAETHES/classes/http%3A%2F%2Fopendata.inrae.fr%2FthesaurusINRAE%2Fc_2ecd2d30

We should see in the @context the @language of the request, like in the following

"@context": {
  "@language": "en"
  "@vocab": "http://data.bioontology.org/metadata/",
  "prefLabel": "http://www.w3.org/2004/02/skos/core#prefLabel",
  "synonym": "http://www.w3.org/2004/02/skos/core#altLabel",
  "definition": "http://www.w3.org/2004/02/skos/core#definition",
  "obsolete": "http://www.w3.org/2002/07/owl#deprecated",
  "semanticType": "http://bioportal.bioontology.org/ontologies/umls/hasSTY",
  "cui": "http://bioportal.bioontology.org/ontologies/umls/cui",
  "inScheme": "http://www.w3.org/2004/02/skos/core#inScheme",
  "created": "http://purl.org/dc/terms/created",
  "modified": "http://purl.org/dc/terms/modified"
}

The language value should be

• The portal language by default
• The request language if the lang parameter is present in the request

The code that handles this is here : https://github.com/ontoportal-lirmm/ontologies_linked_data/blob/master/lib/ontologies_linked_data/serializers/json.rb#L67

works for one class (e.g https://data.testportal.lirmm.fr/ontologies/INRAETHES/classes/http%3A%2F%2Fopendata.inrae.fr%2FthesaurusINRAE%2Fc_25056?lang=fr) but not for classes endpoints (e.g https://data.testportal.lirmm.fr/ontologies/INRAETHES/classes?lang=fr)

@haddadzineddine to fix.

It's already working, but I'm not sure if that's what you had in mind.

For example https://data.testportal.lirmm.fr/ontologies/INRAETHES/classes?language=fr I don't see it
