fix(doc): correct file path format for posts route in routing guide

[babblebey]

This pull request updates the routing documentation for React to clarify the correct file structure for dynamic route segments. The example now uses a slash (/) instead of a dot (.) to indicate dynamic parameters, aligning with the expected convention.

Change Made

• Corrected the example route filename from posts.$postId.tsx to posts/$postId.tsx in docs/start/framework/react/guide/routing.md to accurately reflect dynamic route segment syntax.
