fix: remove shared-config PVC from g10k cronjob, clone r10k config directly

The RWO puppetserver-shared-config PVC caused multi-attach errors when
the cronjob pod was scheduled on a different node than the previous run,
stalling the init container indefinitely. Since the config only needs to
exist for the duration of the job, remove the init container and PVC
entirely and clone the r10k config directly into /shared within the main
container before running g10k.
