Add cspell to node-packages

- This node-packages.nix file in this commit was generated with
  ./pkgs/development/node-packages/generate.sh and then trimmed down in
  order to only commit the new package and dependencies
  Dependencies include:
  - @cspell/dict packages
  - Other cspell libraries
  - Some other JS libraries (e.g. comment-json)
- The vim/plugins/generated.nix file in this commit was generated with
  ./pkgs/applications/editors/vim/plugins/update.py and then trimmed
  down in order to only commit the removal of coc-spell-checker being
  directly in there
- This is to avoid large rebuilds (and make conflicts less likely)
