fix: determine the version of java correctly

[yesudeep]

Fedora Linux has updated its latest JDK to version 22-ea and that breaks the version parsing routine on here.

zsh❯ java --version
openjdk 22-ea 2024-03-19
OpenJDK Runtime Environment (Red_Hat-22.0.0.0.36-1) (build 22-ea+36)
OpenJDK 64-Bit Server VM (Red_Hat-22.0.0.0.36-1) (build 22-ea+36, mixed mode, sharing)

zsh❯ which java
/usr/lib/jvm/java-22-openjdk/bin/java

The rewritten version parser should adapt better.

I'm not sure about how to fix this:

exec ${PAGER:-/usr/bin/less} "$0" || exit 1

Thanks!

The SecurityManager failure is not related, already happening at HEAD. https://buildkite.com/bazel/rules-jvm-external-examples/builds/3809
