[docs] [issue25912] Use __spec__.__name__ instead of __name__ in the docs where appropriate

[Antony Lee]

New submission from Antony Lee:

There are a couple of places in the docs where it would be appropriate to replace __name__ by __spec__.__name__ in order to support the case where the module is executed as the __main__ module:

- logging.getLogger should certainly use __spec__.__name__ so that the logger hierarchy be respected (otherwise, when running "python -mpkg.subpkg", the logger of pkg.subpkg is named "__main__" and thus not a child of the "pkg" logger).

- examples for argparse.ArgumentParser (e.g. in the docs for venv) should use __spec__.__name__ instead of __name__ for the "prog=" argument.

(not guaranteed to be exhaustive)
