bug#56574: 29.0.50; archive-copy-file does not write file under tramp

[pva-outdoor]

Hello, team!

Please try the following scenario:

1. Suppose we have two machines (local and remote) and some '~/1.zip'
   file in remote machine. Open the file via TRAMP from local machine:

   C-x C-f [RET] /ssh:user@remote:1.zip

2. Now select any file inside the archive and save it into remote
   machine (at the same remote directory):

   C [RET]

   The `file.txt' file of zero size appears (but sould be of `file.txt'
   content).

3. Switch to archive `1.zip' buffer and save `file.txt' again:

   C [RET]

   Emacs asks to overwrite remote `file.txt'.

4. Confirm overwriting and chack remote `file.txt' length. It is still zero.


Best regards,
Andrey Petrov.

I've now fixed this in Emacs 29.
