Description

Addresses the ModuleNotFoundError: No module named 'supervision' error that users experience after following the troubleshooting guide for CUDA errors.

Root Cause

When users swap their python_embeded folder with the legacy previous_old_xformers_env.7z environment, they are using a frozen snapshot that predates the introduction of the supervision package (introduced in commit f2a2190). This update adds a clear warning block and a manual installation workaround directly under the relevant troubleshooting section in troubleshoot.md.

Fixes #4140
