Create ci.yml with Install and Docs steps

[glenn-jocher]

@kalenmike @hassaanfarooq01 this preliminary CI action merely tests package installation and Docs publishing.

This action should fail if any docstring issues are present.

🌟 Summary

Implementing Continuous Integration (CI) workflow for Ultralytics HUB-SDK 🚀.

📊 Key Changes

• Introduced ci.yml for GitHub Actions.
• CI triggers on pushes and pull requests to main and develop branches, and also runs daily at 00:00 UTC.

🎯 Purpose & Impact

• Enhanced Quality Assurance: Automatically tests each update, ensuring robust code and documentation quality.
• Efficient Project Maintenance: Helps maintainers quickly identify and resolve integration and documentation issues.
• User Trust and Stability: Users can expect a more reliable and stable HUB-SDK, with fewer bugs slipping into production. 🛠️✨

@kalenmike @hassaanfarooq01 ok guys I've got a super cool CI start here that will help you debug your docs.

There's no code tests yet (though you guys really need to add these), there's only an Install step and a Docs build step. The docs build step fails if any warnings are encountered:

So @hassaanfarooq01 your work is really simple here: go through these warnings and resolve them one by one until the CI is showing a green check mark, then we can merge this PR, and then I can proceed to publish the HUB-SDK reference section over in the ultralytics repo, which is being held up by this.
