Email step w/ SMTP API connection generates smtp_port param typed as int, but default value as a string

[ascott18]

In the parameters of the template, the following gets generated as one of the parameters when there's an Email step with an SMTP API Connection:

"smtp_port": {
  "type": "int",
  "defaultValue": "25",
  "metadata": { /*<stuff>*/ }
}

Then in the template, a Microsoft.Web/connections with a managedApis/smtp type uses this parameter.

I don't think it matters whether it is a string or an int, but the type and default value must agree with one another.

When the type doesn't agree with the value, Azure throws 400 Bad Request errors that. When --debug is provided to the Azure CLI, it can be seen that the error is the result of this type mismatch.
