Restructuring documentation

[neubig]

What problem or use case are you trying to solve?

It would be best to restructure the OpenHands documentation to make it a bit easier to parse.
This can mostly be done by reordering sidebars.ts for now, without changing content.

Proposal

Here is a proposal of top-level and second-level menus:

• Getting Started
• Usage Methods
  • CLI Mode
  • Headless Mode
  • Github Actions
• Advanced Configuration
  • LLM Configuration (previously "LLMs")
  • Custom Sandbox
• Troubleshooting
• Feedback
• For OpenHands Developers
  • Architecture
  • Debugging
  • Evaluation
  • Kubernetes Deployment (previously "Kubernetes")
• About
