Fix container action to properly pass command input

The issue was using environment variable ${INPUT_RUN} instead of
GitHub Actions parameter ${{ inputs.run }}. This caused commands
to be empty in the Docker containers.

Fixed by:
- Reverting to direct parameter substitution ${{ inputs.run }}
- Removing debug code that was interfering with execution
- Keeping PYTHONUNBUFFERED=1 for proper output display

This should restore test output visibility in Linux Docker jobs.
