bluebuild: switch base to ghcr.io/secureblue/kinoite-main-hardened

The 'securecore-kinoite-hardened-userns' image we'd been targeting
does not exist in the secureblue org's package list. Their KDE
Plasma (Kinoite) hardened variant is published as
'kinoite-main-hardened' (or 'kinoite-nvidia-hardened' for NV boxes).
Switch the recipe + all doc references.
