Add shift-backspace keybind alias for backspace (#4937)

Browse source 
When the Kitty Keyboard Protocol is enabled, S-backspace is

typing because it's very easy to accidentally hold shift and press
backspace temporarily when typing capital letters.

Kakoune (which is also a Kitty Keyboard Protocol application) treats
S-backspace as backspace too:
