Show tree-based navigation of projects and subgroups on the Explore public groups page
Description
We are already working on showing projects of subgroups on the parent group page, due in 9.5. This issue proposes to extend that to the explore groups tab as the same use case and benefits apply.
Proposal
Extend the design implemented in https://gitlab.com/gitlab-org/gitlab-ce/issues/30343 to show tree-based navigation of projects and subgroups on the Explore public groups page.
