Docs build fails with instrument view.

[YooSunYoung]

Instrument view for NMX is not needed right now but it was useful for mcstas xml parser,
so I tried to add it in the documentation as well.

But the document build failed due to the output.
It fails complaining about the number of lines. It seems to be related to this issue.

ERROR: Line 404 exceeds the line-length-limit.
WARNING: Each notebook should have at least one section title

It leads to the failure of linking the notebook page to the main page, since it couldn't parse the title of the notebook.
It happened locally and also in the CI build. (The docs build test itself doesn't fail but the notebook is not included in the main page.)

scippneutron doesn't have this issue so there must be a solution.
For now the instrument view is included as a code snippet, not as a cell.

Can you post a link to where this is done? I'd like to look at the code to see if I can figure out what's going on.

Sorry...! Forgot to add the link. It's still in the open PR #18
