[Bug] Docker Build Failing : dependent on depreciated openjdk:17-bullseye image

[KanishkaHalder1771]

Describe the bug
When trying to build from the Dockerfile at docker/server/Dockerfile it throws following error:

docker buildx build --platform linux/amd64 -t ghcr.io/<****>/conductor:test-v1 -f docker/server/Dockerfile --push .

The dockerfile still depends on openjdk:17-bullseye which seems to be depreciated and recently removed from Docker Hub. (I couldn't find exact depreciation date, but I had last ran it on 22nd Sept 2025, it built successfully)
