Fix tag pipeline failures: resolve YAML syntax errors and missing build targets

[Copilot]

This PR fixes the GitHub Actions pipeline that runs when new tags are pushed. The pipeline was failing due to several issues that prevented proper release builds and documentation deployment.

Issues Fixed

1. Missing release Target

The workflow was calling make release but no such target existed in the Makefile. Added a release target that properly calls the existing release.sh script:

release: lib
	./release.sh

2. Invalid YAML Syntax

The workflow used YAML anchors incorrectly, which caused syntax errors:

# Before (invalid)
- *setup_pspdev
- &publish_docs

# After (valid)
- name: Setup PSPDEV Environment
  run: |
    # Proper inline steps

3. Incorrect Directory References

The workflow tried to compress files from a release/ directory, but the release.sh script actually creates files in Distrib/:

# Fixed compression step
tar -czf dist/oslib-release-${GITHUB_REF##*/}.tar.gz Distrib/

4. GitHub Pages Authentication Failure

The ghpages target was using SSH authentication which doesn't work in GitHub Actions. Updated to use HTTPS with the GitHub token:

git remote add remote https://x-access-token:${GITHUB_TOKEN}@github.com/dogo/oslib.git

5. Build Artifacts Management

Added Distrib/ and OSLib.zip to .gitignore to prevent build artifacts from being committed to the repository.

Testing

• ✅ Validated YAML syntax with python -c "import yaml; yaml.safe_load(open('.github/workflows/Build.yml'))"
• ✅ Verified release.sh script creates files in expected Distrib/ directory
• ✅ Confirmed make release target now works correctly

The tag pipeline should now successfully build releases and deploy documentation when new tags are pushed.
