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.

Test failure (Parsed an error from text content: undefined RangeError: Incorrect locale information provided) is unrelated: jupyterlab/jupyterlab#17079

Same remark about adding quotes for labels.

@krassowski, thanks for the review! I updated all the settings text to properly reflect the actual section headers. Let me know if there is anything else I should do to close out this PR.

JupyterLab 4.3.4 fixed the issue with "Incorrect locale information provided", I restarted the tests - let's see if everything passes.

It looks like query strings in the visual regression test code need updating?

@krassowski, I'm not sure why the table-context-menu is failing.
