The target state (phase one)

1- Default portal language (done) :

From https://data.stageportal.lirmm.fr/ontologies/INRAETHES/classes/http%3A%2F%2Fopendata.inrae.fr%2FthesaurusINRAE%2Fc_2ecd2d30
We show the prefLabel and synonyms of the default portal language (english), as already done now

2- Add request language parameter:

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

we should display this in the API

"prefLabel": "absorptiométrie biphotonique à rayons X",
"synonym": [
		"densitométrie minérale osseuse",
		"ostéodensitométrie"
]

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

we should display this in the API (current default)

"prefLabel": "dual x-ray absorptiometry",
"synonym": [
		"dual-energy x-ray absorptiometry",
		"osteodensitometry",
		"DXA",
		"bone densitometry",
		"DEXA"
]
