Automatic Docker image publishing to Docker Hub

[bburda]

Summary

Set up GitHub Actions workflow to automatically publish Docker images to Docker Hub:

• latest tag on every push to main
• Version tag (e.g., v1.2.3) on GitHub release tags

---

Proposed solution

Create .github/workflows/docker-publish.yml with Job

Additional context

Usage after implementation:

# Always latest from main
docker pull selfpatch/sovd_web_ui:latest

# Specific version
docker pull selfpatch/sovd_web_ui:1.2.3

# Run
docker run -p 8080:80 selfpatch/sovd_web_ui:latest

Let's use my personal DockerHub bburda/sovd_web_ui since we don't have a selfpatch orgnization yet.

edit: Switched to ghcr.io instead of DockerHub.
