Update: Fixed incorrect method name

I've just pushed a correction to fix an inaccuracy in the documentation. The method name was incorrectly documented as _rsm_generateResponse() throughout, but the actual implementation in the source code uses _handleStreamGeneration().

Changes made:

• ✅ Updated method name in "Required implementation" section
• ✅ Fixed ResumableStreamAgent interface definition
• ✅ Corrected message flow description
• ✅ Updated complete example code

The documentation now accurately reflects the actual API as implemented in the resumable-stream-chat example.

✅ Documentation update complete

Added comprehensive API reference documentation at /agents/api-reference/resumable-streaming.mdx to complement the existing how-to guide.

What's new:

• Technical API reference page with detailed implementation examples
• Clear separation between reference documentation (API details) and tutorial content (how-to guide)
• Following the Diátaxis framework for documentation structure

The PR now includes both:

1. API Reference (/api-reference/resumable-streaming/) - Technical docs for developers looking up the API
2. How-to Guide (/guides/resumable-streaming/) - Step-by-step tutorial for implementing the feature

Both pages follow Cloudflare docs style guide requirements and use proper MDX components.
