adapted cssh to ubuntu 26.04
because gnome changed: ```md 1. What Changed Between Ubuntu 20.04 and 26.04? Ubuntu 20.04 (GNOME 3.36) In older versions of gnome-terminal (e.g., 3.36.x), profiles were automatically registered in the org.gnome.Terminal.ProfilesList schema when they were created via dconf or the GUI. The list key in org.gnome.Terminal.ProfilesList was dynamically updated to include any profile that existed in /org/gnome/terminal/legacy/profiles:/. Result: You could create a profile (e.g., via dconf write), and gnome-terminal would automatically recognize it, even if you didn’t explicitly add it to the list key. Ubuntu 26.04 (GNOME 46+) In newer versions of gnome-terminal (e.g., 3.58.x or later), the list key in org.gnome.Terminal.ProfilesList is now strictly enforced. Profiles must be explicitly added to the list key to be recognized by gnome-terminal. Result: If you create a profile via dconf but don’t add it to the list key, gnome-terminal will ignore it and fall back to the default profile. ``` - took this opportunity to rewrite cssh in python for clarity
