kyma.resource.status.state metric gets filtered by namespace filter

[a-thaler]

Description
I have a MetricPipeline like that:

spec:
  input:
    otlp:
      namespaces:
        include:
        - cap
    runtime:
      enabled: true
      namespaces:
        include:
        - cap
        - observability

The pipeline exports the health metric "kyma.resource.status.conditions" but not "kyma.resource.status.state". The missing metric is namespace specific (kyma-system) and most probably gets blindly filtered out by the otlp input namespace selector.

Expected result

The metric is always emmitted

The reason for this bug is probably because we forgot to update the otlpInputSource() function to also exclude the scope metric.InstrumentationScopeKyma in the returned expression.

This otlpInputSource() function is used when creating the config for the namepace-filter processor https://github.com/kyma-project/telemetry-manager/blob/main/internal/otelcollector/config/metric/gateway/config_builder.go#L187-L190
