Describe the feature request

This has been a known issue for a while: #167

However, never is it mentioned in the readme, which is why I broke our CI/CD today 🙃
I double tested everything on a windows machine besides the single quotes.

The readme currently states:

Cross platform (including Windows)

shortly after followed by:

Remember to surround separate commands with quotes:

concurrently 'command1 arg' 'command2 arg'

There should be a warning and an example about windows needing escaped double quotes:

concurrently \"command1 arg\" \"command2 arg\"

Not everybody has the luxury of being able to test on different operating systems, when other people rely on it.
And if they do, they might forget 😅
