Documentation: Remove external dependence on pygments.

Current documentation uses syntax highlighting in 'sphinx'
via 'pygments' library. This leads to build failures on the
systems with old version of this library.

In fact that only 'windows.rst' uses highlighting it's a
very simple change. This helps us to avoid build issues
on different systems and allows to remove painful external
dependency.
