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.

Comece pela documentação de os.exec* na seção vinculada library/os.html#os.execl e compare-a com a seção Process management. Revise o PR vinculado gh-125565 antes de começar; o trabalho estará concluído quando o argumento obrigatório do caminho do executável estiver documentado com as funções e a discussão sobre as variantes estiver mais clara.
