docs(fern): fix redirects for /latest/index.html (#793)

Google and external links target .../openshell/latest/index.html. Wildcard rules .../latest/:path*/index.html can mis-resolve when the path segment is empty, producing a literal :path* in the destination URL.

Add explicit redirects for /openshell/latest/index.html and /openshell/latest/index (aligned with NeMo-Curator fern/docs.yml) and document ordering versus Sphinx-style URLs.
