Investigate version-destroy-ttl for google secret manager secrets

Google announced a new feature to prevent deletion of secrets

https://cloud.google.com/blog/products/identity-security/introducing-delayed-destruction-a-new-way-to-protect-your-secrets

To do this we need to create a version-destroy-ttl on secrets created.

The Terraform resource supports this https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/secret_manager_secret.html#example-usage---secret-with-version-destroy-ttl

So we can add it to instrumentor https://gitlab.com/gitlab-com/gl-infra/gitlab-dedicated/instrumentor/-/blob/main/gcp/onboard/modules/secrets/secrets.tf?ref_type=heads
