subprocess module docs contain an inconsistent mix of repeated versionchanged descriptions

首先查看 subprocess 模块文档和 issue 101283，然后比较 Popen、run()、call()、check_call() 和 check_output() 的 versionchanged 与 versionadded 注释。检查这些 API 中对 cwd、input、text、encoding 和 errors 的文档说明方式。完成的标准是这些注释遵循一致的策略，且没有重复或相互冲突的描述。

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.
