[Docs]: 404/NotFound page on Chroma docs get confusing

The Not Found / 404 page in Chroma docs are a little confusing. Due it's showing a code fragment that in a quick view you think it's part of some documentation or link you've opened (see image attached below)


I think a better approach can be a simple Not Found message with a redirect link to the home or something.

Start by locating the Chroma documentation site's 404 or Not Found page and inspect how it currently renders the code fragment shown in the issue. Replace that confusing presentation with a clear Not Found message and a link to the documentation home, then verify the result by visiting an invalid documentation URL.
