data/tls_certificate: Updating real world testing for new www.terraform.io certificate results

[bflad]

Terraform CLI and Provider Versions

N/A

Terraform Configuration

data "tls_certificate" "test" {
  url = "https://www.terraform.io/"
}

Expected Behavior

Existing acceptance testing passes.

Actual Behavior

Existing acceptance testing is failing, presumably because the terraform.io certificates rolled.

Steps to Reproduce

1. terraform apply

How much impact is this issue causing?

Low

Logs

No response

Additional Information

Similar to #516, except we likely want to keep these tests as-is (since real world testing is important for this provider) and just update the value checks. We could potentially loosen those checks slightly to allow for SSL certificate updates without failing these acceptance tests.
