❓ Type of change

• 📖 Documentation (updates to the documentation or readme)
• 🐞 Bug fix (a non-breaking change that fixes an issue)
• 👌 Enhancement (improving an existing functionality like performance)
• ✨ New feature (a non-breaking change that adds functionality)
• 🧹 Chore (updates to the build process or auxiliary tools and libraries)
• ⚠️ Breaking change (fix or feature that would cause existing functionality to change)

📚 Description

This adds a basic GitHub Pages preset. It creates a .nojekyll file and by default uses https://github.com/tschaub/gh-pages as deploy command.

✅ TODO

• docs (including GH Actions workflow?)
• rethinking deploy command
• base URL support - this may need to be documentation

📝 Checklist

• I have linked an issue or discussion.
• I have updated the documentation accordingly.
