[Bug] `datadog_dashboard.slo_list_defintion` panics on plan, apply when in a`group_definition `

Terraform Version

terraform 1.2.3 and terraform-provider-datadog v3.17.0

Affected Resource(s)

Please list the resources as a list, for example:

datadog_dashboard, in particular datadog_dashboard.slo_list_definition

If this issue affects multiple resources, it may be an issue with Terraform's core, so please mention this.

Terraform Configuration Files

resource "datadog_dashboard" "board" {
  layout_type = "ordered"
  notify_list = []
  reflow_type = "auto"
  title       = "test"

  widget {
    group_definition {
      layout_type = "ordered"
      widget {
        slo_list_definition {
          title = "SLOs"
          request {
            request_type = "slo_list"
            query {
              query_string = "env:prod"
              limit        = 10
            }
          }
        }
      }
    }
  }
}

Debug Output

When running a terraform import for a dashboard that includes the slo_list_definition widget

│ Error: object contains unparsed element: map[requests:[map[query:map[limit:10 query_string:env:prod] request_type:slo_list]] title:SLOs type:slo_list]

Panic Output

If Terraform produced a panic, please provide a link to a GitHub Gist containing the output of the crash.log.

Expected Behavior

What should have happened?

The plugin does not panic during a plan or apply
Be able to import the resource into terraform when a slo_list_defintion is in a group_defintion

Actual Behavior

What actually happened?

A terraform apply creates the resource then panics
A terraform plan panics when refreshing remote of the datadog_dashboard resource
terraform import fails to import

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

From the example terraform code above,

terraform apply
- Find the Dashboard in Datadog
terraform plan
terraform import datadog_dashboard.board <id>
