Add Route53 record dependencies

[amontalban]

Without this the module was trying to create Elasticsearch resources before the DNS entry and therefore the cluster was created:

module.acm[0].aws_acm_certificate_validation.this[0]: Creating...
module.acm[0].aws_acm_certificate_validation.this[0]: Creation complete after 0s [id=2023-08-03 19:26:52.495 +0000 UTC]

Error: Get "https://elk.domain.com/": dial tcp: lookup elk.domain.com on 10.1.0.2:53: no such host

  with elasticsearch_index_template.index_template["live_transcription_events"],
  on index_template.tf line 1, in resource "elasticsearch_index_template" "index_template":
   1: resource "elasticsearch_index_template" "index_template" {

With this change the Cluster is created, then the Route53 host and all Elasticsearch resources are created properly.

Additionally, I added a change to the examples folder to make sure tflint checks pass.
