Fix Docker build version detection

- Skip prebuild step in Docker when VERSION build arg is provided
- Prevent version-check.js from overwriting pre-generated version.js in Docker
- Fix Docker containers showing incorrect '-dev' suffix for release builds
- Use direct react-scripts build when version is pre-generated
