Describe the issue you're reporting

As done in open-telemetry/opentelemetry-collector/pull/11683 and open-telemetry/opentelemetry-collector/pull/11793 (followed by open-telemetry/opentelemetry-collector/pull/11940), we would benefit from automatically generating replaces on these files to ensure that the release automation does not fail because of it (see e.g. #37242 and #37244 that were needed to do a test release).
