Windows: Add Windows Subsystem for Linux documentation (#23515)

* Windows: Add Windows Subsystem for Linux documentation

As discussed during the Windows Working Group meeting we do want
documentation on running Ansible on Windows as it may help grow
the Windows/Ansible community and does work out-of-the-box.

However we do take care to emphasize that WSL is not fit for
production use.

* Update intro_windows.rst

Edits for mechanics and clarity.
