Add more info on the scheduler group issues

• [BUG] - Jupyter scheduler doesn't run successfully unless users are in developer group. nebari#2444
• Raise more informative error message when user doesn't have adequate permissions argo-jupyter-scheduler#9.

Despite what these two issues say, the docs are correct. Jobs are scheduled even if only the admin group is used. I've just double-checked. An error is also already shown when there's a permission error. So I've just added more information on how the groups should be configured and some troubleshooting info.

Documentation

Access-centered content checklist

Text styling

• The content is written with plain language (where relevant).
• If there are headers, they use the proper header tags (with only one level-one header: H1 or # in markdown).
• All links describe where they link to (for example, check the Nebari website).
• This content adheres to the Nebari style guides.

Non-text content

• All content is represented as text (for example, images need alt text, and videos need captions or descriptive transcripts).
• If there are emojis, there are not more than three in a row.
• Don't use flashing GIFs or videos.
• If the content were to be read as plain text, it still makes sense, and no information is missing.

Note: I use single backticks here on purpose: it allows showing the entire message inline and wraps it around to content width while still formatting it as monospace. Using three backticks would either make it too long (if one line) or would require breaking it into multiple lines (but then it would be harder for users to find this message if they search the docs by error message).

This image pretty much duplicates the text above, but I think it's nice to have both here. The textual error is good for search and the image is good for figuring out where to look or how it should look in the UI.

Thanks for double-checking it, @nkaretnikov. This looks good to me already, though can you also add an FAQ section on this error? Maybe describe it lightly in the FAQ and point to this document for a general overview.

@viniciusdc Added FAQ, moved notes closer to the beginning of the page. Added paragraphs, so they could be referenced. PTAL.
