Fix incompatible pointer types for GtkItemFactoryCallbacks on gcc-14

The GtkItemFactoryEntry struct callback is of type GtkItemFactoryCallbacks
(aka void (*)(void)) but is initialised with GtkItemFactoryCallback1 types
(aka void (*)(void *, guint, GtkWidget *)).

This is coherent with the gtk-2 documentation:
> gtk_item_factory_create_items(..., GtkItemFactoryEntry *entries,...)
> entries : an array of GtkItemFactoryEntrys whose callback members must by of
> type GtkItemFactoryCallback1

But, under gcc-14, the implicit cast from GtkItemFactoryCallback1 to
GtkItemFactoryCallback triggers an incompatible-pointer-types error (See [gcc-doc]).

An exemple of this error:

pidgin/gtkconv.c:3096:66: error: initialization of 'void (*)(void)' from incompatible pointer type 'void (*)(void *, guint, GtkWidget *)' {aka 'void (*)(void *, unsigned int, struct _GtkWidget *)'} [-Wincompatible-pointer-types]
3096 | { N_("/Conversation/New Instant _Message..."), "<CTL>M", menu_new_conv_cb,
| ^~~~~~~~~~~~~~~~
pidgin/gtkconv.c:3096:66: note: (near initialization for 'menu_items[1].callback')

To fix this, explicitely cast to GtkItemFactoryCallback where needed.

Testing Done:
Built with gcc-14, started and clicked on some affected menus
