[Doc] Documented simplest example contains wrong variable names

[Dohbedoh]

Description

The current documented simple example shows the variable hostname and temp_license:

module "eks_blueprints_addon_cbci" {
  source = "REPLACE_ME"

  hostname     = "example.domain.com"
  cert_arn     = "arn:aws:acm:us-east-1:0000000:certificate/0000000-aaaa-bbb-ccc-thisIsAnExample"
  temp_license = {
    first_name  = "Foo"
    last_name  = "Bar"
    email = "foo.bar@acme.com"
    company = "Acme Inc."
  }

}

But the variable names are actually hosted_zone and trial_license.

Actually the full definition would be like

module "eks_blueprints_addon_cbci" {
  source  = "cloudbees/cloudbees-ci-eks-addon/aws"
  version = "~> 3.16720.0"

  hosted_zone    = "example.domain.com"
  cert_arn     = "arn:aws:acm:us-east-1:0000000:certificate/0000000-aaaa-bbb-ccc-thisIsAnExample"
  trial_license = {
    first_name  = "Foo"
    last_name  = "Bar"
    email = "foo.bar@acme.com"
    company = "Acme Inc."
  }

}
