feat(harmonyos): update documentation and chat context provider

- Updated the documentation in the HarmonyOS Extension README file to include information about the remote API being used.
- Modified the HarmonyOSChatContextProvider to provide more context information.
- The context now includes the main language used (TypeScript, JavaScript, or ArkTS) and mentions the Flutter-like UI framework being used.
- This will enhance the user experience when working with HarmonyOS projects.
