[WIP] build: switch to Jena SNAPSHOT

[berezovskyi]

Description

Switch to the latest Jena SNAPSHOT (4.10.0-SNAPSHOT) to anticipate Jena 5 breaking changes. So far we only had to replace usage of the shaded Guava classes (my fault for using them in the first place) and use ReifierStd instead of Statement.listReifiedStatements().

This PR also deals with JDK 17 warnings where possible.

Just migrated from Jena 4.10 SNAPSHOT to 4.11 SNAPSHOT, build succeeds on 17 and 21.

Jena now publishes 5.0 SNAPSHOT too, we could test how we fare.

Bad news, org.apache.jena.rdf.model.ReifiedStatement and org.apache.jena.rdf.model.SimpleSelector are not found in Jena 5. @Jad-el-khoury you will have to look into this, I don't have time to go through the Jena commits and mailing list to figure out further migration steps. Happy to see that Jena made another 4.x release in the meantime.
