fix(about): call guidata's get_python_libs_infos

plotpy.widgets.about.get_python_libs_info and the plotpy-benchmarks
header called guidata.widgets.about.get_python_libs_info, which does not
exist (renamed by mistake with the "infos" to "info" renaming of PlotPy's
own functions), and raised AttributeError.

The benchmark header now uses PlotPy's get_python_libs_info, which also
gives the version of PlotPy.
