SyntaxWarning: invalid escape sequence '\.'

[antonsoroko]

Describe the bug

Not a "real" bug, but I noticed SyntaxWarning during upgrade to 1.6.6 on ubuntu 24.04 with python 3.12.
iirc python 3.12 does not like when raw strings are used as normal strings (i guess you wanted to use raw string r'.', but i might be wrong.)

Include the following information:

• OpenSnitch version: 1.6.6
• OS: Ubuntu
• Version: 24.04
• Window Manager: KDE5
• Kernel version: 6.8.0-36-generic

To Reproduce
sudo apt install ./opensnitch_1.6.6-1_amd64.deb ./python3-opensnitch-ui_1.6.6-1_all.deb

Post error logs:

/usr/lib/python3/dist-packages/opensnitch/dialogs/prompt.py:608: SyntaxWarning: invalid escape sequence '\.'
  appimage_path = os.path.dirname(con.process_path).replace(".", "\.")

Expected behavior (optional)

Screenshots

Additional context

[akhepcat]

Apparently in newer pythons, the regular expressions should be written as raw strings: r"..." or have the backslashes quoted in the string

raw strings should be backward compatible.

(this is according to bug reports to hplip for the same thing)
