Update all test-only dependencies

Major updates: These have some breakages, but no source changes are necessary on our end.

* jline 3.30.4 → 4.1.0.
* biz.aQute.bnd.annotation 6.3.1 to 7.2.3.
* mockito 3.7.7 → 5.23.0.
* hamcrest 2.2 → 3.0.

Minor updates:

* JUnit Jupiter → 5.14.4 and JUnit Platform → 1.14.4. (The major upgrade to JUnit 6.0 is left for later.)
* assertj 3.26.3 → 3.27.7.
* java-diff-utils 4.12 → 4.16.
* snakeyaml 2.2 → 2.6
* jcommander 1.81 → 1.82
