d/aws_route53_zone: permit both name and zone_id arguments (#37686)

As part of the migration of the `route53` service to AWS SDK V2, an `ExactlyOneOf` constraint was added to the `name` and `zone_id` arguments in the `aws_route53_zone` data source. This is technically a regression as the data source functioned correctly in earlier versions when `name` is set and `zone_id` is an empty string. This change reverts the constraint and adds an acceptance test to cover this potential configuration.
