What happened?

Update Default MachineCIDR from 10.x to 192.168.0.0/16 network.

#See the troubleshooting documentation (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md) for ideas about what information to collect.

#For example,

# If the installer fails to create resources (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md#installer-fails-to-create-resources), attach the relevant portions of your `.openshift_install.log.`
# If the installer fails to bootstrap the cluster (https://github.com/openshift/installer/blob/master/docs/user/troubleshootingbootstrap.md), attach the bootstrap log bundle.
# If the installer fails to complete installation after bootstrapping completes (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md#installer-fails-to-initialize-the-cluster), attach the must-gather log bundle using `oc adm must-gather`

# Always at least include the `.openshift_install.log`

No new nightly builds are available after 16th June, for verifying the fix.
Latest is dated 06-16 (https://mirror.openshift.com/pub/openshift-v4/ppc64le/clients/ocp-dev-preview/4.11.0-0.nightly-ppc64le-2022-06-16-003709)

Verified this with a new 4.11 nightly build - '4.11.0-0.nightly-ppc64le-2022-06-21-133338
The specification in the generated 'install-config.yaml' reflects the changes made.
