We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Include a suggestion to update frontend (Jupyterlab, ...) in mimetype error
Follow-up that comes out of #2585. Raised by @joelostblom:

> do you think we need to communicate the minimum version of JuptyerLab that support Altair 5 somewhere? I am thinking ideally directly in the error message if possible, but otherwise at least in the docs and release notes, what do you all think?
