Remove versions from inventory sample (#12164)

The recommended usage of kubespray is to use the default versions.
So putting them in inventory/sample is not really very helpful, and
causes:
- churn (keeping the inventory/sample up to date)
- support issues (mismatch between defaults and sample inventory)

Remove all concrete versions from the inventory sample.
