Confusing error message when rename target is an open file

Bug report

Bug description:

Background

Writing a tool to update and rename some files, I made a mistake and tried to rename a file while it was still open. This works on Linux, but raises an error when writing to a Windows network shares. This is known and documented - see Path.rename docs.

The issue

The problem I have is that the error message is incorrect. It says "FileNotFound", which is confusing because the files do exist. If I had got a more useful message, I would have worked out what the problem was with my tool much sooner.

Repro case

    file1 = Path("test1.txt")
    file2 = Path("test2.txt")
    file1.open("w").write("file 1 text\n")
    file2.open("w").write("file 2 text\n")
    with file1.open():
        file2.rename(file1)

Outcomes;
On linux, writing to pwd or a linux network share, file is rewritten without error.
On linux, writing to a Windows network share, an incorrect error message is given.

$ python test.py
Traceback (most recent call last):
  File "/home/jontwo/test.py", line 17, in <module>
    main()
  File "/home/jontwo/test.py", line 13, in main
    file2.rename(file1)
  File "/usr/lib/python3.12/pathlib.py", line 1363, in rename
    os.rename(self, target)
FileNotFoundError: [Errno 2] No such file or directory: 'test2.txt' -> 'test1.txt'

On Windows, writing to pwd, a useful error message is given.

c:\temp>python test.py
Traceback (most recent call last):
  File "c:\temp\test.py", line 16, in <module>
    main()
  File "c:\temp\test.py", line 12, in main
    file2.rename(file1)
  File "C:\OSGeo4W\apps\Python312\Lib\pathlib.py", line 1363, in rename
    os.rename(self, target)
FileExistsError: [WinError 183] Cannot create a file when that file already exists: 'test2.txt' -> 'test1.txt'

CPython versions tested on:

3.12

Operating systems tested on:

Linux, Windows

Commencez par reproduire le cas pathlib.Path.rename présenté dans l’issue sous Linux et dans des conditions de partage réseau Windows. Examinez pathlib.py autour du point d’entrée rename signalé et comparez les erreurs obtenues avec le comportement documenté de Path.rename. Le travail est terminé lorsque le cas où la cible est ouverte ne présente plus de message FileNotFound trompeur et que le comportement spécifique à la plateforme est couvert par des tests appropriés.
