Documentation for os.exec* functions omits information about required argument

Documentation

All of the os.exec* functions (there are 8) require the path to the executable to be the first argument given to the executable, as well as specified in the path or file parameter of the exec method. The documentation of the exec* functions doesn't include any information about this requirement, however it can be found at the start of the Process management section of the documentation. I think it should be moved to the exec* function documentation.

Additionally I personally think that the discussion of the different variants of the function is a bit confusing and would be easier to understand if it was structured differently and a few headings were added.

I have some ideas about how to do this and intend to put together a pull request addressing the issues.

Comienza con la documentación de os.exec* en la sección enlazada library/os.html#os.execl y compárala con la sección Process management. Revisa el PR enlazado gh-125565 antes de comenzar; el trabajo estará terminado cuando el argumento requerido de la ruta del ejecutable esté documentado con las funciones y la discusión de las variantes sea más clara.
