Warn users about MINGW64 Windows incompatibility with slash (/) arguments

Docs: Add warning for Bash users about slash (/) being misinterpreted as a path

Summary

This documentation update adds a warning to help users avoid issues when using Commander CLI tools in Git Bash / MINGW64 on Windows. In these environments, passing / as a flag value (e.g., --separator "/") may result in unexpected behavior due to auto-expansion into C:/Program Files/Git.

I suspect MINGW64 will get used less now there are full shells with WSL, but it will still catch some people.

I think using a different character for this example program would avoid the problem. Lots of special characters across multiple shells!
