Add a button in Marzban Next that leads to Marzban document

[iamtheted]

Hi

I believe it would be really helpful to add a button in Marzban Next that takes us to Marzban document.
Currently, Marzban users have to find the document through external sources including Telegram group or Marzban Nameh channel and I think including it inside the panel would be really great, so you may want to keep this in mind for the future!

Let me know what your thoughts are on this matter,
Thank you
