Terraform Configuration Files

version 4.61.0 adds stack_type to resource `ha_vpn_gateway, but wants to destroy and recreate the vpn_gateway resource.

resource "google_compute_ha_vpn_gateway" "vpn_gateway" {
provider = google-beta
name = each.value.gateway
network = each.value.network
region = each.value.region
project = each.value.project
}

# Copy-paste your Terraform configurations here.
#
# For large Terraform configs, please use a service like Dropbox and share a link to the ZIP file.
# For security, you can also encrypt the files using our GPG public key:
#    https://www.hashicorp.com/security
#
# If reproducing the bug involves modifying the config file (e.g., apply a config,
# change a value, apply the config again, see the bug), then please include both:
# * the version of the config before the change, and
# * the version of the config after the change.

19:05:13        + stack_type = "IPV4_ONLY" # forces replacement
19:05:13          # (2 unchanged attributes hidden)
19:05:13

19:05:13            - ip_address = "x5.xxx.xxx.xxx" -> null
19:05:13          }
19:05:13      }
19:05:13 

Steps to Reproduce

Terraform forces a replacement of the resource, which is not expected as the default if not specified according to the google API docs below is IPV4_ONLY, so this addition isn't really changing any thing other than updating the config in the remote state
