multimod: Fix to log 'Using versioning file' and 'Successfully deleted module tags' to stderr instead of stdout

[pellared]

This will help to get rid of:

• | grep -v "Using" in https://github.com/open-telemetry/opentelemetry-collector/blob/4ae8d2bcd5ae2e72280fb6af7e9402b7b6e7c6cb/Makefile#L402 and https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/ea1632ea7ae6bcf4c92f049a4fe053dd802a77a4/Makefile#L156
• https://github.com/signalfx/splunk-otel-go/pull/2994
