Add jdkVendor parameter support to Maven Wrapper Plugin

Complete the JDK management feature by adding vendor selection support:

✅ Plugin Enhancement:
- Add jdkVendor parameter with default value 'temurin'
- Support for multiple JDK vendors: temurin, corretto, zulu, liberica, oracle, graalvm
- Write jdkVendor property to maven-wrapper.properties file
- Integrate with existing jdkVersion parameter

✅ Testing Results:
- Successfully generated wrapper with: -Djdk=17 -DjdkVendor=temurin
- Properties file correctly contains: jdkVersion=17, jdkVendor=temurin
- Shell script successfully downloaded JDK 17.0.14 from Temurin
- SDKMAN API integration working: resolved major version to latest patch
- Cross-platform JDK management fully functional

This completes the shell-based JDK management implementation for
only-script distribution type, providing a robust alternative to
Java-based JDK management without chicken-and-egg problems.
