* Change default values for authorized_ranges from {} to null and
gcp_public_cidrs_access_enabled from false to null in the
access_config.ip_access variable. This ensures the dynamic
master_authorized_networks_config block is properly
conditional on user input.
Previously, these fields would never be null due to their
default values, causing the block to always be initialized
even when users didn't intend to configure authorized networks.
* remove explicit null
* Remove all defaults for access_config.ip_access. Fix permadiff.
* Fix tests
* Swap try with coalesce
