python: use gi.require_version() in generate-setting-docs.py and examples

gi now emits a warning when not loading a specific library
version [1]:

  ./generate-setting-docs.py:21: PyGIWarning: NM was imported without specifying a version first. Use gi.require_version(NM, 1.0) before import to ensure that the right version gets loaded.
    from gi.repository import NM, GObject

Seems require_version() is reasonably old to just always use it without
breaking on older versions [2].
