Fix Dockerfile: Replace deprecated openjdk base image with amazoncorretto:17

Summary

This PR updates the Dockerfile to replace the deprecated or unavailable openjdk:17/openjdk:17-jdk base image with amazoncorretto:17. This resolves Docker build errors due to missing manifests for the previous base images and ensures consistent JDK vendor usage in both the build and runtime stages.

Details

• Changed the runtime stage in the Dockerfile from:
  • FROM openjdk:17 or FROM openjdk:17-jdk
  • to: FROM amazoncorretto:17
• Fixes image pull/build error:

  MANIFEST_UNKNOWN: manifest unknown; unknown tag=17-jdk
  

• Keeping both build and runtime stages on Corretto 17 improves compatibility and stability.

How to verify

• Rebuild and redeploy the Docker image.
• The image build should complete successfully without manifest/tag errors.
• The application should launch normally on port 8080.
