Update log6x-input-spec-filter-namespace-container.adoc

The type field in RHOL 6.0 documentation is missing from the Filtering application logs configuration.

https://docs.openshift.com/container-platform/4.17/observability/logging/logging-6.0/log6x-clf.html#log6x-input-spec-filter-namespace-container_logging-6x

-type field is missing in the above configuration.
-type field filed is required while configuring ClusterLogForwarder with the inputs section.
-spec.inputs.type is required
-type should be `application` here in above configuration.

It needs to look like the following:

~~~
apiVersion: observability.openshift.io/v1
kind: ClusterLogForwarder
# ...
spec:
  serviceAccount:
    name: <service_account_name>
  inputs:
    - name: mylogs
      application:
        includes:
          - namespace: "my-project" 
            container: "my-container" 
        excludes:
          - container: "other-container*" 
            namespace: "other-namespace" 
      type: application             <<=== Need to add this line
~~~
