Correcting mistakes from Copilot

PyQt5.QtOpenGL's widget is called "QGLWidget" (QOpenGLWidget is QT6).
We don't currently expose GrGLMakeNativeInterface() in skia-python.
And, defaultFramebufferObject() is not a method in "QGLWidget".

skia.GrGLMakeNativeInterface() exists, but is behind a
"#if !defined(SK_DISABLE_LEGACY_GL_MAKE_NATIVE_INTERFACE)" and
probably should not be used directly.
