Cannot rebind <Command-Q> to the None action on macOS

$ alacritty --version
alacritty 0.16.1 (42f49ee)

To reproduce:

1. Add the above version of Alacritty to your $PATH
2. (In a temporary directory)
   1. echo 'keyboard.bindings = [{ key = "Q", mods = "Command", action = "None" }]' > config.toml
   2. alacritty --config-file config.toml
   3. Observe that sending <Command-Q> performs the "Quit" action, whereas I would expect it to perform the "None" action as bound

I would also be satisfied if there was a strong case for not permitting rebinding this keybind, but given that "Quit" is an action listed in alacritty(5), it seems to me the maintainers intended for it to be able to be rebound.
