az repos policy create can't read file

Start in azext_devops/dev/repos/policy.py at create_policy_configuration_file and its json.load call. Reproduce the Windows PowerShell-generated template with az repos policy create --config, then inspect how the file is opened and how the command handles the reported JSONDecodeError. Done means the command can read the described file without this failure.

I create a file manually and named if template.json
I did some token replacement and saved it using this command
Out-File -FilePath $templateFile -InputObject $updatedContents

Whatever output PS outputs is not recognized by az repos policy create --config - probably UTF-8

I changed it to ASCII encoding and it worked fine
Out-File -FilePath $templateFile -InputObject $updatedContents -Encoding ASCII

Command Name
az repos policy create Extension Name: azure-devops. Version: 0.26.0.
