Proper docs for windows option??

[webketje]

The documented posixSlashes (or outdated unixify) options do nothing.
The only way the docs provide a way not to convert the backslashes into forward slashes is by providing a custom format function.
But that is awkward to use as the docs discourage replacing backslashes with forward slashes explicitly.

What should be happening?

• Remove any mentions to posixSlashes and unixify in the docs
• Add docs for the windows option

This issue has come up twice on picomatch and there is even a commit that fixes it
micromatch/picomatch@dbe5d92, however it seems not to be included in the master branch.

I lost an hour debugging this thinking there was something wrong at my end, and it's all the more strange that the picomatch changelog mentions a switch from unixify to windows since 2019 (!) but nothing about posixSlashes?

FWIW I thought posixSlashes was a much more declarative name for the option.
PS: there's a typo in the examples under posixSlashes that says require ('picomatch')
