`curses.__version__` documented but does not exist

Documentation

curses.__version__ has not existed in any stable python version, and can be removed from the documentation.
https://docs.python.org/3/library/curses.html#curses.__version__

➜  ~ uvx python@3.14 -c 'import curses ; curses.__version__'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: module 'curses' has no attribute '__version__'

(same results for py 3.8 through 3.14)

If I'm not stepping on anyone's toes, I would like to make the PR to fix this as my first PR to cpython, once a course of action is agreed upon. I believe it would just be removing curses.__version__ from the documentation, and I don't think it needs a changenote as the attribute hasn't existed for a while.

The __version__ attributes inside the standard library are being deprecated generally, see gh-76007. 👍 to making a PR to remove from the docs.
