change: add replace_keycodes=false to expr mappings (#190)

neovim/neovim#19598 changed `vim.keymap.set` to
replace keycodes by default for all mappings if `expr == true` instead of
only luaref expr mappings.

The toggle expr mappings are not luarefs but shouldn't have the keycodes
replaced since they use `<Plug>`.
