[Documentation] Minor clarification for macOS

This applies to Linux users as well, or anyone using zsh. I've also faced teh same issue earlier. the issue is shell-specific rather than OS-specific - zsh requires quotes around the brackets because it treats square brackets as special characters for globbing (also known as pathname expansion), so they need to be quoted to be interpreted literally.

the reason this affects macOS by default is that macOS has used zsh as the default shell since Catalina, where [] are treated as glob patterns for character classes. However, many Linux users(like myself) have also switched to zsh and would encounter the same issue.

I think the note should be updated to reflect this:

# Note: zsh and some other shells require quotes around brackets:
pip install -e ".[dev]"
