NO-JIRA: variants: simplify

+## Variants
+
+To support building both a RHEL-based and a CentOS Stream-based CoreOS, the
+coreos-assembler concept of [variants] is used. The following variants are
+supported:
+
+- `rhel-9.4`: RHEL 9.4-based CoreOS; including OpenShift components.
+- `c9s`: CentOS Stream-based CoreOS, including OpenShift components. This
+  currently includes some packages from RHEL because not all packages required
+  by OpenShift are provided in CentOS Stream.
+
+The default variant is `rhel-9.4`.
