[BUG]: billing_email should not be required for github_enterprise_organization

[Nothing4You]

Expected Behavior

resource "github_enterprise_organization" "org" {
  enterprise_id = data.github_enterprise.mine.id
  name          = "orgname"
  display_name  = "orgname"
  description   = "orgdesc"
  admin_logins = [
    "myuser",
  ]
}

should work

Actual Behavior

resource "github_enterprise_organization" "org" {
  enterprise_id = data.github_enterprise.mine.id
  name          = "orgname"
  display_name  = "orgname"
  description   = "orgdesc"
  billing_email = "dummy-placeholder@mydomain.tld"
  admin_logins = [
    "myuser",
  ]
}

is required, despite billing emails not being configurable in github web. this applies at least to EMU orgs on github.com. the provided value seems to be effectively ignored.
