subprocess module docs contain an inconsistent mix of repeated versionchanged descriptions

Documentation

The subprocess module documentation has an explosion of repeated text in versionchanged or versionadded markers splattered over multiple APIs within the docs.

The reality is that many of these are technically all directly Popen API changes, that the other higher level preferred more user friendly APIs like run() and call() and check_call() and check_output() all make use of internally and forward a majority of their arguments to.

Examples to look for: where are cwd, input, text, encoding, errors argument behavior changes/additions mentioned vs which APIs accept these.

I noticed this when looking over the changes made in https://github.com/python/cpython/issues/101283 where it became apparent to me that we're not internally consistent in how we do this within the doc today. The doc needs some cleanup and a strategy for this.

Inizia esaminando la documentazione del modulo subprocess e la issue 101283, quindi confronta le note versionchanged e versionadded per Popen, run(), call(), check_call() e check_output(). Controlla come cwd, input, text, encoding ed errors sono documentati in queste API. Il lavoro è completato quando le note seguono una strategia coerente, senza descrizioni ripetute o in conflitto.
