Update distr-tracing-tempo-config-default.adoc

- One TempoStack configuration parameter is incorrectly placed
- Here is the documentation link: https://docs.redhat.com/en/documentation/openshift_container_platform/4.15/html/distributed_tracing/distributed-tracing-platform-tempo#distr-tracing-tempo-config-default_distr-tracing-tempo-configuring
- In the `Example TempoStack CR` configuration `spec.managementState` indentation is wrong.
- Here is the current configuration:
~~~
apiVersion: tempo.grafana.com/v1alpha1 1
kind: TempoStack 2
metadata: 3
  name: <name> 4
spec: 
managementState: managed 21
~~~
- All other parameters are correctly mentioned.
- We need to change the ``spec.managementState` indentation.

-Here is the correct config:
~~~
apiVersion: tempo.grafana.com/v1alpha1 1
kind: TempoStack 2
metadata: 3
  name: <name> 4
spec: 5 
  managementState: managed 21
~~~
