Which problem is this PR solving?
This PR introduces a conditional unref feature to the Prometheus Exporter within the OpenTelemetry JavaScript project. Previously, the unref method was called unconditionally, which could lead to potential issues in environments where unref is not available or not needed, thus keeping the process open unnecessarily. This change enhances compatibility and reliability, especially in diverse runtime environments.
