Support kitty key modifiers in keybindings (#13906)

# Description
hi hi, this makes the parsing of modifier key combos in config more
general, and adds support for additional kitty keyboard protocol
modifiers. It seems that support for [kitty
keys](https://sw.kovidgoyal.net/kitty/keyboard-protocol) had already
been added to nushell in https://github.com/nushell/nushell/pull/10540,
and this was the only missing piece to making them available in
keybindings.

# User-Facing Changes
- keybindings in config can include the super, hyper and meta modifiers
(e.g. `modifier: super`, `modifier: shift_super`, etc.), and these
modifiers will work in supporting terminals (kitty, foot, wezterm,
alacritty...)
- all permutations of snake_cased modifier combinations now behave
equivalently for the purpose of describing keybindings in config (e.g.
`control_alt_shift` was previously supported where `shift_control_alt`
was a config error — now they're the same)

# Tests
None of this looks to be tested at the moment. I only found a smoke test
under the nu-cli crate, and I couldn't break tests elsewhere by stuffing
around with modifier handling. Works on my machine, though! 🌈
