[Bug] Data Stream settings are not persisting in index template

[poiriermike]

Describe the bug
data_stream setting for elasticstack_elasticsearch_index_template is not persisting on subsequent runs

To Reproduce

1. Create an index template
2. Modify index template settings (tested by modifying priority
3. Re-run terraform plan (will show changes, but nothing about data stream)
4. Run terraform apply. Will remove the data stream property from the ojbect

Expected behavior
Data stream settings are preserved on update

Debug output
Run terraform command with TF_LOG=trace and provide extended information on TF operations.
