[FLINK-38503] Adapt DefaultClusterClientServiceLoader to java 25

[snuyanzin]

What is the purpose of the change

The problem is that in jdk 25 there are bugs https://bugs.openjdk.org/browse/JDK-8350481 and https://bugs.openjdk.org/browse/JDK-8196182
which result into throwing NoClassDefFoundError while hasNext for ServideLoader
Unfortunately it was fixed only for jdk27. The PR is to adapt behavior of DefaultClusterClientServiceLoader for java25

Also I have java25 CI in my own Azure setup https://dev.azure.com/snuyanzin/flink/_build/results?buildId=4811&view=results where this fix is applied (together with some others which will come in other PRs). Before this change none of e2e was able to pass, now 2 passes, others are able to go further however still under investigation
