Fixing newrelic_yml resource for distributed_tracing_enable

[aaroncline]

We use newrelic_yml in several of our cookbooks. After updating to newrelic 2.39.0, we starting getting failures related to the recent feature addition of distributed tracing enabling.

Here's the error:

================================================================================ Error executing actioncreate` on resource 'template[/opt/newrelic/java/ir-newrelic.yml]'

This addition fixed the issue for us.
