neovim: Keymap updates

- new: `ctrl + ,` opens Neovim's `init.lua`
- new: `]q` `[q` to traverse quickfix list
- new: `<leader>cq` adds project diagnostics to quickfix list
- remove: `<leader><enter>` to apply setting changes; lazy doesn't
  support it
- remove: `<A-jk>` to move lines; can move with `J`, `K` with visual
  selection by default
