Don't cast GtkWrapMode to the incompatible enum PangoWrapMode

The enum values are not compatible, and moreover, there is an extra
GTK_WRAP_NONE that PangoWrapMode doesn't have - thus,
pango_wrap_mode_to_string() will assert.

As far as I can tell, Orca does not read the wrap-mode key in the
dictionary for text attributes, anyway.

Fixes: #4869
