fix: update Alpine version to 3.20 for stable package repositories

- Change base image from node:22-alpine to node:22-alpine3.20
- Resolves package installation issues with Alpine 3.21 repositories
- Ensures stable access to build dependencies (python3, gcc, etc.)

This change fixes the Docker build process by using a more stable
version of Alpine Linux that has reliable package repositories.
