Revert "Merge branch 'update-supported-features-for-group-security-dashboard-docs' into 'master'"
What does this MR do?
Reverts https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/10044/diffs because it has an item that will be introduced in 11.10 and since we needed to be picked into stable, better revert and re-open another MR with the right docs.
