Terraform Configuration Files

provider "github" {
  token        = var.prow_oauth_token
  organization = "MyOrg"
}

resource "github_repository_webhook" "prow" {
  repository = "MyRepo"

  configuration {
    url          = "https://prow.myexample.com/hook"
    content_type = "json"
    insecure_ssl = true
    secret       = var.github_webhook_prow_secret
  }

  active = true
  events = ["*"]
}

Actual Behavior

The GitHub Webhook is properly created, but the "SSL Validation" is not disabled.

Steps to Reproduce

I'm using the Terrafrom code mentioned above to create GitHub Webhook.
In the code above you can see the I would like to disable SSL Validation by setting the parameter insecure_ssl = true.

The GitHub Webhook is created by Terraform properly, but the SSL Validation is not disabled - see the screenshot:

If I manually click in GitHub Web GUI to "Disable" the webhook is working fine like it should be - but I can not do it via Terraform now.

Thanks for looking at it.
