Add FAQ and Troubleshooting pages

We should have two pages: one of miscellaneous questions, and another of common errors and how to work around them. Examples:

• troubleshooting: torch + rosetta + napari crashes Python: viewer.add_labels crashes napari 0.5.3 on Mac M1 (using Rosetta + Torch) napari#7259
• troubleshooting: "module napari has no attribute Viewer" when doing an editable install on top of a normal one, or when you have a local file napari.py
• faq: how do I use napari in a remote Jupyter env?

how do I use napari in a remote Jupyter env?

This one (on my to-do) is probably more than a FAQ answer I think...

Yes, sorry, in this case I meant it would have a quick response "napari is a native app so it's not possible to do this directly within a notebook or lab tab, we are aware of this issue, but currently there are some options to use napari in a remote desktop, see this page" [include a link to a page with all the options].
