update Jena to v4.0

[zlatent]

apache-jena-4.0.0 was lately released, https://jena.apache.org/download/. any plan to update the Docker file to use Jena 4.0 in place of 3.17?

There might be some changes to the command line tools but let's just try right away on our master (due rename to main?) which Docker Hub builds as devel.

I don't see from the 4.0.0 release notes any big changes in terms of Fuseki. Adding RDF* support would be nice!

Changed my mind on the branches..

Making branch jena4 for now, built with tag jena4 for both Docker images.

Jena 4 build is happy (after merging #52 #53), and likewise on Docker Hub.

Could some of you help try out a bit better than me?

So far, so good! Tested validating and uploading a .jsonld file. Apache Jena is of course very good at keeping backwards compatibility even when bumping major version!

Will tag and update tomorrow. Merged into master so you can also in a few minutes try on devel tag, which would include #51 for Ctrl-C support.
