🔀 变更说明 | Description of Change

Hi there, since LobeChat has a Langfuse integration for observability, I added a documentation page that describes how to set this up. 🙂

I would suggest to place it under "Advance Usage" in the Docs. However, I did not find the config file that edits the sidebar. It would be great if you could add this to my PR!

If you have any additional questions, you can also reach out to me via our shared Discord channel with you! I am also happy to provide a Chinese version of the page if you think this would make sense :)

@jannikmaierhoefer Hi Jannik, Thanks for your PR! I suggest to place the docuement into self-hosting/advanced observability/langfuse.mdx. Becausse langfuse intergation only can be enabled with self-hosting mode.

And we will update the menu after this PR is merged.

Thanks again for your contribution!
