dspace context content type

Bug Report

Describe the Bug

Not sure if it's a bug or have some sort of side effect, but currently when resolving the dspace context it returns application/json as content type instead of application/ld+json

[mkollenstart]

I'm not aware of any side effects of having the content type as application/json instead of application/ld+json.
The only way of changing this is by changing the file extension to .jsonld instead of .json due to the handling of content types by Github Pages

Fixed with perma-id/w3id.org#4673 - both for odrl.json and dspace.jsonld
