Description:
When the Red Hat build of OpenTelemetry operator is not installed in the default namespace of openshift-opentelemetry-operator, metrics collection will fail even if the openshift.io/cluster-monitoring: "true" label exists on the namespace that it has been installed in. 

Additionally the following TargetDown alerts are visible in the OpenShift Web Console:

• 100% of the opentelemetry-operator-webhook-service/opentelemetry-operator-webhook-service targets in <installed-namespace> namespace have been unreachable for more than 15 minutes. 
• 100% of the opentelemetry-operator-controller-manager-metrics-service/opentelemetry-operator-controller-manager-metrics-service targets in Namespace <installed-namespace> have been unreachable for more than 15 minutes.

Environment: 
opentelemetry-operator.v0.107.0-4-0.1727168137.p

Reproduction Steps:

1. Create a namespace. This namespace can't have the name of openshift-opentelemetry-operator. 
2. Add the label openshift.io/cluster-monitoring: "true" to this namespace.
3. Install the operator as normal.

Workaround:

Uninstall the operator and reinstall it in the openshift-opentelemetry-operator namespace.
