fix(build): avoid managed Node runtime in Alpine images

[DigHuang]

Summary

• replace the root devEngines runtime download with a Node.js >=22.22.0 engine requirement
• refresh pnpm-lock.yaml to remove the managed node@runtime package
• keep existing Alpine Dockerfiles unchanged

Problem

pnpm binds workspace scripts to the downloaded devEngines runtime. The official Node.js runtime artifact is not usable in the Alpine/musl builder, leaving the node shim pointed at a missing executable and breaking the volume-manager image build.

Verification

• built projects/volume-manager/Dockerfile successfully with frozen lockfile on arm64
• built the same image successfully for linux/amd64 with Docker Buildx
• reran the Docker build after rebasing onto the latest upstream/main
• git diff --check
