Describe the bug
Parler-tts backend imports runtime_version from protobuf and fails.

To Reproduce

1. Install parler-tts model from gallery
2. Try to invoke the model
3. curl -L http://localhost:8080/tts \ -H "Content-Type: application/json" \ -d '{ "model": "parler-tts", "input": "Hi there!" }' | aplay

Expected behavior
Model loads and generates audio for the text

Should be covered by #3954 - we had a hacky workaround in place for workarounding descriptinc/audiotools#111

Still present on master images. Needs deeper investigation
