Moving Ray Clusters restructuring section to be subpage under existing Ray Clusters. (#27036)

This PR puts the Ray Clusters (under construction) docs section (see #26754) under Ray Clusters as a subpage.

This makes the master branch docs clean and presentable for users
Ray Clusters doc writers can use existing CI to iterate on the docs, without having a massive PR once we're done.
