Fix bare-metal conditional in installation-configuration-parameters
Fix bare-metal conditional in installation-configuration-parameters

https://github.com/openshift/openshift-docs/pull/38463 ended up
disabling all sections that were conditional on "bare" instead of
limiting the changes to dual-stack related sections.  This prevents
other uses of the "bare" conditional from working as expected.
