Description

raw.githubusercontent.com sends file as text/plain ,
and Jena 3.3.0 has a regression reading such URL:
In 3.20, the real content-type used to be recognized from URL ending, but not anymore.

How to reproduce: org.apache.jena.riot.RDFDataMgr.loadGraph("https://raw.githubusercontent.com/jmvanel/rdf-i18n/master/foaf/foaf.fr.ttl")
