Remote kernel cannot start

[fakeGenuis]

A fancy way of starting a remote kernel is though https://github.com/emacs-jupyter/jupyter?tab=readme-ov-file#starting-a-remote-kernel, but it get emacs stuck in the latest release 30.1. I found the minimum code to reproduce it is like

(let ((file "/ssh:aaa:/home/bbb/foo1.txt"))
  (with-timeout (2.5 (delete-file file))
    (while (file-exists-p file)
      (accept-process-output nil 0.25))))

which correspond to

jupyter/jupyter-env.el

Line 182 in db8a9e2

(jupyter-with-timeout

of function jupyer-session-with-random-ports. It always stuck in 30.1 while works fine in 29.4, the reason is unclear to me. But since for remote file, (interrupt-process process) at above line only interrupt local process and don't remove remote file, so maybe we can change function call around to something like below to solve it?

        (jupyter-with-timeout
            (nil (if (file-remote-p conn-file) 0 jupyter-default-timeout)
                 (delete-file conn-file))
          (not (file-exists-p conn-file)))

Also, org src block to reproduce this issue
