syncplay: Syncplay doesn't start on Python 3.12

Describe the bug

I am on Fedora 39 beta which ships with Python 3.12 and unable to ./syncplayClient.py.

└┌(%:~/src/github.com/syncplay/syncplay)┌- ./syncplayClient.py --help  
Traceback (most recent call last):
  File "/home/aminda/src/github.com/syncplay/syncplay/./syncplayClient.py", line 14, in <module>
    from syncplay import ep_client
  File "/home/aminda/src/github.com/syncplay/syncplay/syncplay/ep_client.py", line 3, in <module>

    from configparser import SafeConfigParser, DEFAULTSECT
ImportError: cannot import name 'SafeConfigParser' from 'configparser' (/usr/lib64/python3.12/configparser.py). Did you mean: 'RawConfigParser'?

To Reproduce Steps to reproduce the behavior:

1. git clone ...
2. mkdir venv
3. python3 -m venv venv
4. . venv/bin/activate
5. python3 -m pip install requirements.txt
6. ./syncplayClient.py

If I use python3.10 or python3.11, it will work, same with pypy3 which is 3.10.2. <del>I haven’t tried 3.11 which didn’t work on another project (https://github.com/editorconfig-checker/editorconfig-checker.python/issues/28).</del>
