Split the Helm chart reference

Backports #11292

This will make it easier to navigate to different values settings for
each chart, since values can have their own H2 sections that are
distinct from chart names. (Previously, both chart names and values
settings were organized into H2 section headings.)

This will also mean that edition warnings for Cloud users can be more
visible, since we can place them at the top of a page for a given chart.

See #10636
