The flag `--userns-host` is now required to enable the user namespace isolation for build containers. By default, this is disabled, which resolves the incompatibility with Docker plugins that don't support "userns as host" functionality. This reverts the default behavior from pack 0.35.0 where user namespace isolation was enabled by default, while still allowing users who want this feature to opt in.
