Cannot `os.spawnl` with no arguments

Bug report

Bug description:

Python 3.8 and 3.11.9

Probably related to: https://github.com/python/cpython/issues/52284
Seems to be the same as: https://github.com/python/cpython/issues/63130

A number of bugs:

1. • Doesn't work with no arguements.

>>> os.spawnl(os.P_NOWAIT, "c:\path_to_some_program\app.exe")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<frozen os>", line 930, in spawnl
ValueError: spawnv() arg 2 cannot be empty

2. If I try and make the arguement empty it also fails. This means that I am forced to send an arguement that may trigger an unknown behaviour in the spawned application.:

>>> os.spawnl(os.P_NOWAIT, "c:\path_to_some_program\app.exe", '')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<frozen os>", line 930, in spawnl
ValueError: spawnv() arg 2 first element cannot be empty

2. If any aspect of this is intended, then the documentation needs to be updated to explicitly say this. Currently it implies any arguments are optional. (Honestly, the docs for this are bad generally.)

CPython versions tested on:

3.11

Operating systems tested on:

Windows

Comienza con la implementación de os.spawnl mostrada en el traceback y la documentación correspondiente de spawnl y spawnv. Reproduce los casos de Windows sin argumentos y con un primer argumento vacío; después, determina el comportamiento previsto y actualiza la implementación o la documentación para que los requisitos de los argumentos aceptados sean explícitos y estén cubiertos por pruebas.
