[BUG] Yazi and Nano from ML4W settings

[Gianfilippo980]

Describe the bug

Editing the System section of the Settings menu to select Yazi as a file manager and Nano as editor works fine for the shortcuts but not for the buttons inside the configuration menu itself.
It would also be nice if the $EDITOR environmental variable could be set accordingly, instead of needing to add a .bashrc_custom file.

Steps to reproduce

1. Go to the ML4W sidebar app (blue button on the top-right);
2. Click the "settings" button in the top-middle;
3. Go to the "System" tab;
4. Set the File Manager to $(cat /home/gboccia/.config/ml4w/settings/terminal.sh) -e yazi or $(cat ~/.config/ml4w/settings/terminal.sh) -e yazi or kitty -e yazi;
   5.Click the folder icon on the top-right of that same configuration page.

Expected behavior

I expect TUI apps to open a terminal and reach the relevant configurations files when pressing menu buttons, same as they do when shortcuts are used.
In a previous install, I was able to use TUI apps from the configuration menu itself, as long as I avoided the relative path (starting with ~), given that this happens for both the editor and file manager, I need to locate the configuration files without the help of the menu.
