configparser.InvalidWriteError: Cannot write key r8169_0_6100:00,0; contains delimiter :

Step 3: Reproduce the problem:

1. get a MinisForum MS-S1 Max, Install Fedora Linux 43 and s-tui.
2. Run s-tui.
3. Navigate to "Save Settings" and press enter.

see also: #239 (comment). This is a very similar bug that can probably be fixed the same way.

Changing the second instance of configparser.ConfigParser() to configparser.ConfigParser(delimiters="=") in s_tui.py on line 833 fixes the problem.
