docs(tooltip): showcase rich tooltip and document both variants

Adds a 'Rich tooltips' section to the example app (full title/content/actions
variant plus a body-only one), registers the RichTooltip page in the docs
component map so the generated docs cover Tooltip.Rich, and cross-references
the rich variant from the plain Tooltip JSDoc.
