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

When the Kitty Keyboard Protocol is enabled, S-backspace is distinguished from backspace with no modifiers. This is awkward when 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: https://github.com/mawww/kakoune/blob/3150e9b3cd8e61d9bc68245d67822614d4376cf4/src/input_handler.cc#L1275
