Summary

🔀➕🗂️

This pull request reorganizes and updates the documentation for running and deploying applications on Radius. It splits the Deploy via CLI page into two pages: Run apps and Deploy apps, and adds tabs for different scenarios. It also adjusts the weight and category of the Deploy via GitHub Actions page.

We're running apps on Radius, we're deploying with the CLI
We're changing weights and categories, we're moving content to the sky
We're splitting parameters into tabs, we're making docs more clear
We're the masters of the code review, we're the rebels of the sphere
