Why aren't we using --noconfirm here?

This is unfortunately not working due to the default shell in Hetzner's recovery environment being dash (I assume).

I disabled the ansible-lint rule so we can avoid set -o pipefail which isn't supported in Hetzner's recovery environment.

Thanks for the contribution @xenrox :)
