Description of Change
Updated the Windows launcher template to use JAVA_HOME to locate the Java executable when JAVACMD is not set. If %JAVA_HOME%\bin\java.exe exists, it is used; otherwise, the launcher falls back to the default Java executable (java) on the system PATH.
This change allows the Dependency-Check CLI to run on Windows when JAVA_HOME is configured but java.exe is not present on the PATH, while preserving the existing behavior for users who set JAVACMD or rely on PATH.

Fixes #8631
This fixes issue #8631, where the CLI fails on Windows if JAVA_HOME is configured but java.exe is not on PATH.
Have test cases been added to cover the new functionality?
This change updates the Windows launcher script only. The behavior was verified manually by testing the following scenarios:
JAVA_HOME configured and java.exe not on PATH → CLI starts successfully.
JAVACMD configured → launcher uses JAVACMD.
JAVA_HOME not configured but java.exe available on PATH → existing behavior is preserved.
