[pygobject] overrides: Remove Pango.Context.get_metrics

[Simon Feltman <sfeltman src gnome org>]

commit 2d388fcfca4bf1258d01b4491b4168589f3dd2b0

    overrides: Remove Pango.Context.get_metrics
    
    Remove the override for Pango.Context and the get_metrics method. This can
    be done now that tail end method arguments with "allow-none" are implicitly
    defaulted to use None/NULL.
