application/n-triples MIME-Type is not supported for CONSTRUCT queries

[aindlq]

Did not find any supported media type in this 'Accept:' header field: "application/n-triples;q=0.7, text/plain;q=0.7". Currently the following media types are supported: application/sparql-results+json, application/sparql-results+xml, application/qlever-results+json, text/tab-separated-values, text/csv, text/turtle, application/octet-stream

From quick look it seems that produced Turtle is equals to NTriples format - https://github.com/ad-freiburg/qlever/blob/d2782a4b728cb073d4f62af2bd48f00f44f0d7f8/src/engine/ExportQueryExecutionTrees.cpp#L61-L65 So text/turtle actually gives NTriples.
