Add GitHub Actions workflow to publish Docker images to GHCR

[bbartels]

Summary

• Adds a GitHub Actions workflow to automatically build and publish Docker images to GitHub Container Registry when releases are published
• Supports manual workflow dispatch for ad-hoc builds

Features

• Multi-architecture builds (linux/amd64, linux/arm64)
• Automatic semantic version tagging (e.g., release v1.2.3 creates tags: 1.2.3, 1.2, 1, latest)
• GitHub Actions build caching for faster subsequent builds
• Manual trigger option via workflow_dispatch
• Zero configuration required - uses built-in GITHUB_TOKEN

Admin Setup Required

None! The workflow uses the built-in GITHUB_TOKEN and automatic packages: write permission.

After the first publish, the package will appear at:
ghcr.io/<org>/<repo> (e.g., ghcr.io/tableau/tableau-mcp)

Optional: Package Visibility

By default, packages inherit the repository's visibility. If needed, admins can adjust package settings at:
Settings → Packages → tableau-mcp → Package settings

Usage

Pull the image:

docker pull ghcr.io/<org>/tableau-mcp:latest

Test Plan

- Create a test release and verify image appears in the repo's Packages tab
- Verify multi-arch support: docker manifest inspect ghcr.io/<org>/tableau-mcp:latest
- Test manual workflow dispatch from Actions tab

Hey @bbartels, thanks again for submitting this PR.

Would it be alright with you if one of us internally resubmitted this PR with these changes? That would make it so you wouldn't need to mess with signing the CLA and we can iterate quickly if any follow-up changes are necessary without needing to bug you. :)
