Title: docs/make.bat: Fix Sphinx invokation on Windows

Sphinx doesn't have installer and therefore is never
available from PATH on user system unless user adds
it manually. Sphinx can only be installed with
`python`, which is added to system PATH, so it is
more reliable way to execute Sphinx in Windows.
