Ability to remove default key mappings in chat window

[bootleq]

Currently we can't directly remove a default key mapping, for example, remove <C-S> in insert mode from below:

chat = {
  keymaps = {
    send = {
      modes = { n = "<C-s>", i = "<C-s>" },
    },
  },
},

Would it be good if we can set the i value to false or something to delete it?
