Update pygame's portmidi to 2.0.4

[MateusRodCosta]

Fixes #316

Tested as working when building against fdo 23.08

[bbhtt]

More work is needed to get pygame building on 24.08:

src_c/font.c:584:12: error: assignment to ‘Uint16 *’ {aka ‘short unsigned int *’} from incompatible pointer type ‘char *’ [-Wincompatible-pointer-types]
  584 |     buffer = Bytes_AS_STRING(obj);
      |            ^
In file included from src_c/pygame.h:32,
                 from src_c/font.c:32:
src_c/font.c: In function ‘font_init’:

And this is only one, there are several other errors that need to be fixed.

will handle some of them

Well, I believe I will build dtipbijays with my own fork of shared-modules and fdo runtime.
Sorry, but I am not that good at C to contribute with patches for the compilation errors.
