chore: Update variable name to tag_specifications

[LuisValdesZero]

In service/main.tf it is used a plural tag_specifications name for the attribute

Description

In the service it is used reference for a plural tag_specifications but in variables.tf the variable name is singular tag_specifications, this makes the deployment to break, after changing to plural it works again.

In file modules/service/variables.tf we have singular tag_specification

terraform-aws-ecs/modules/service/variables.tf

Line 286 in bf5bdcd

tag_specification = optional(list(object({

But in modules/service/main.tf we have plural tag_specifications

terraform-aws-ecs/modules/service/main.tf

Line 245 in bf5bdcd

for_each = managed_ebs_volume.value.tag_specifications != null ? managed_ebs_volume.value.tag_specifications : []

          dynamic "tag_specifications" {
            for_each = managed_ebs_volume.value.tag_specifications != null ? managed_ebs_volume.value.tag_specifications : []

            content {
              resource_type  = tag_specifications.value.resource_type
              propagate_tags = tag_specifications.value.propagate_tags
              tags           = tag_specifications.value.tags
            }
          }
