Subject: [PATCH] Update using-image-builder.adoc

Updated the image-builder command examples for the simplified installer image type.                                                       Without the --ignition-config flag, the tool currently
triggers a nil pointer dereference error at line 1088. This change
ensures the documentation matches the tool's internal requirements.
