Support starting a kitty debugging window with the 'kitten' command

Support starting a kitty debugging window with the 'kitten' command. Essentially while doing this works:

context.terminal = "kitty @ launch --location=before --cwd=current --bias=65".split()

it is deprecated, and one should do this:

context.terminal = "kitten @ launch --location=before --cwd=current --bias=65".split()

P.S. I'm no longer encountering this issue: #2471 (comment)

Ah wait this breaks contextoutput in pwndbg..

Sending SIGTERM allows gdb (and it's scripts) to gracefully exit which is important for stuff like this https://github.com/joaogodinho/pwnmux?tab=readme-ov-file#usage that needs to close the extra windows.
