WinRM Connection Returns 401

#### Overview of the Issue

I am trying to build a GCP Windows Image but seems like the WinRM connection is not working. Also `packer build -debug` does not print the credentials for the Administrator user. In AWS, `packer build -debug` retrieves the password properly.

#### Reproduction Steps

Using the following template as per the docs and other attributes

```
source "googlecompute" "windows-example" {
project_id = var.project_id
source_image_project_id = ["windows-cloud"]
source_image_family = "windows-2019"
#source_image = "windows-server-2019-dc-v20200813"
zone = "us-east4-a"
disk_size = 50
machine_type = "n1-standard-8"
communicator = "winrm"
winrm_username = "packer_user"
winrm_insecure = true
winrm_use_ssl = true
tags = ["packer"]
preemptible = true
image_labels = {
server_type = "windows-2019"
}
metadata = {
windows-startup-script-cmd = "winrm quickconfig -quiet & net user /add packer_user & net localgroup administrators packer_user /add & winrm set winrm/config/service/auth @{Basic=\"true\"}"
}
account_file = var.account_file_path
}

build {
sources = ["sources.googlecompute.windows-example"]
}
```
