Move from Java 11 to Java 17

[lhstrh]

The latest LTS version of Java is version 17, and it comes with a number features (e.g., text blocks) that are of help for some of our code generators that are currently still written in Xtend. For that reason alone, it would be great if we could move to Java 17.

It looks like Java 17 support is being worked on in eclipse-xtext/xtext#1982. With the release of v2.6.0 (apparently due on Jan 31), we should attempt to bump our Java dependency as well.

Note this:

Xtext now supports running on Java 17 with Java 8 and 11 targets. Source and Target 17 are not supported yet and are planned for Xtext 2.27.0. This will also require dropping Java 8 in the next release.

This means that until 2.27.0 we apparently won't be able to use Java 17 syntax...

Note that this also requires bumping gradle, our current gradle version (6.5) only supports up to Java 14

Noted. We have already done this successfully in another branch called ‘release’. Xtext 2.26.0 also uses Gradle 7.
