Support Temurin JDKs with JMOD files (#1149)

* Initial plan

* Add Temurin JMOD installation support

* Rebuild action bundles

* Use java-package for Temurin JMODs

Copilot-Session: e7d8c581-2d14-4ccc-aeca-afc0f3b0c2bc

* Fix Temurin JMOD test paths on Windows

Use platform-aware path construction for the JMOD copy and cache assertions so the Windows test expects backslash-normalized paths.
