Fix documented type of wxART_XXX constants

They're (now, and had always been before the recent changes) string
literals, i.e. of type "const char *", rather than "wxString".

+    @note When building with @c wxNO_IMPLICIT_WXSTRING_ENCODING defined (see
+          @ref overview_string for more details), you need to explicitly use
+          wxASCII_STR() around these constants.
+
     Additionally, any string recognized by custom art providers registered using
     wxArtProvider::Push may be used.
