[Bug] Data View Namespaces Field Null during import

**Describe the bug**
When importing a data view to the terraform state file the namespaces field is set to null despite it being shared with all spaces and the api showing namespaces: ["*","default"]

**To Reproduce**
Steps to reproduce the behavior:
1. TF configuration used '...'
2. TF operations to execute to get the error '...' [e.g `terraform plan`,`terraform apply`, `terraform destroy`]
3. See the error in the output '...'
1. Import a data view
2. terraform import
3. View tfstate file
**Expected behavior**
I expect the namespaces field to match what the kibana api returns for data views.

**Debug output**
Run `terraform` command with `TF_LOG=trace` and provide extended information on TF operations. **Please ensure you redact any base64 encoded credentials from your output**.

[DEBUG] provider.terraform-provider-elasticstack_v0.11.0: Authorization: Basic xxxxx==
