build(tauri): enforce Java 17+ requirement in Windows jlink build script (#5684)

# Description of Changes

This pull request improves the `scripts/build-tauri-jlink.bat` build
script by adding a check to ensure that Java 17 or higher is installed
before proceeding. This helps prevent build errors due to incompatible
Java versions.

Build process enhancements:

* Added logic to parse the installed Java version and verify that it is
at least version 17; the script now exits with an error message if an
older version is detected.
* Updated status messages to clearly indicate the Java version being
used and to provide feedback if requirements are not met.
