Issue with single SAN provisioning

[SergK]

Hi,

I'm trying to use this module with the only one SAN, please see below

data "aws_route53_zone" "this" {
  name         = "example.com"
  private_zone = false
}

module "acm" {
  source = "git::https://github.com/terraform-aws-modules/terraform-aws-acm?ref=v2.4.0"

  domain_name = "example.com"
  zone_id     = data.aws_route53_zone.this.zone_id

  subject_alternative_names = [
    "*.api.example.com",
  ]

  wait_for_validation = true
  validation_method   = "DNS"
}

and it fails with error:

module.acm.aws_acm_certificate_validation.this[0]: Creating...

Error: 1 error occurred:
	* missing *.api.example.com DNS validation record: _xxxxxxxxxxxxxxxxxxxxxxxxxxxx.api.example.com

  on .terraform/modules/acm/main.tf line 40, in resource "aws_acm_certificate_validation" "this":
  40: resource "aws_acm_certificate_validation" "this" {

terraform version
Terraform v0.12.6
+ provider.aws v2.35.0

At the same time, if there are more then one records in subject_alternative_names no issue exists

This has been fixed in #32, please use v2.5.0 of this module.
