Open a new subpage for Error messages

[CAnorbo]

Open a new page on docs that describes all the status messages at least from the music box, but would be great later to extend it for all error messages.

The structure should be something like this, but can be different:
- Message1
--What does it mean?
--What can I do?
- Message2
--What does it mean?
--What can I do?

This can increase the UX because there is a way to find solutions for my problems, and also could decrease the support requests with really general questions.
