non-docable files error out doc page

[crowlKats]

Any non-docable file will error out the page, ie https://deno.land/std@0.136.0/Releases.md. these should redirect to their code alternative. https://github.com/denoland/dotland/blob/22925d0ee7f8e0b5c1669ebc9aaa8b7c7843e940/util/doc.ts#L36

I was going to report this a few days ago 😅 note this only applies to /std, not /x.

[crowlKats]

yea, though this would apply to /x as soon as we enable docs there, which hopefully isnt too far off. quick-fix would be try-catch the whole content of the function and return null if there is an error
