Linux: Add another terminal emulator

[quivenda]

For Linux, only support 3 terminal emulators, which is:

1. gnome-terminal
2. konsole
3. xterm

Can you please add another terminal emulator such as alacritty or kitty ?

Also, there was some typo on log

could not fina terminal emulator on system -> could not find terminal emulator on system

Will do.

And thanks for mentioning the typo.
