build.sh fails on Mac OS with recent clang (was fixed in MicroPython)

I'm trying to add my library to the Community Bundle but when I go to run `build.sh` I get errors like this while building `mpy-cross`:
```
GEN build/genhdr/qstrdefs.generated.h
In file included from ../py/emitnx64.c:16:
../py/emitnative.c:2267:5: error: variable length array folded to constant array as an extension [-Werror,-Wgnu-folding-constant]

-e See https://learn.adafruit.com/building-circuitpython; Adafruit Discord #circuitpython-dev
make: *** [build/py/emitnx64.o] Error 1
```

This was fixed in MicroPython a couple of weeks ago; see https://github.com/micropython/micropython/issues/18116
and it was fixed by https://github.com/micropython/micropython/commit/33cf1ab3ccabecd156176ceebcd56332e8a5d325

And it was fixed in CircuitPython 10.0.0.

However, it looks like `build.sh` wants to build CircuitPython 9.2.4 instead of that.

Empieza inspeccionando build.sh para encontrar dónde se selecciona CircuitPython 9.2.4 y, después, compara esa elección con la corrección referenciada de MicroPython y con CircuitPython 10.0.0. Actualiza la selección de compilación para que clang de macOS reciente pueda compilar mpy-cross y verifica que el script finaliza sin el error indicado.
