Feature Request

This is my very first issues, so many thanks to all of you for maintaining and contributing the project 💚

Just a brief idea for a feature.

Have you consider to add GitHub Actions integration? Other commonly used tools (e.g., Ruff, Prettier) have their own reusable actions, so I guess this would nice to have such an option for djLint.

Thanks!
