Tycho 5 needs Java 21 to run the build, so CI now uses JDK 21; the bundles still target Java 17. Assisted-by: multiple AI agents and layers of automated tooling 🤖

This moves the build from Tycho 4.0.13 to the current 5.0.4 release, which brings almost a year of fixes in p2 resolution, the download transport and the test runtime. Tycho 5 must run on Java 21, so the CI workflow now sets up JDK 21; the bundles keep their JavaSE-17 execution environment, as Tycho still compiles for older Java releases. CONTRIBUTING.md now lists the Java 21 and Maven 3.9.9 requirements for building, and the Maven wrapper already uses 3.9.9.
