[chore] Add dev script for easier development loop (#16)

This PR adds a npm "dev" script. Upon executing `npm run dev`, the project will be served (default port 3035) in "watch" mode, every local change of the files will refresh the page.

This change should enable faster development loop.

Conflicts:

  field).
  Ported upstream changes.
- `config/i18n-tasks.yml`:
  Upstream added `simple_form.overridden` to `ignore_unused`,
  we had `simple_form.glitch_only`.

Merge upstream changes

Merge commit 'dc09c10fa8cc9230bf14e48d790c8f0c26043f8f' into glitch-soc/merge-upstream

Conflicts:
- `.rubocop_todo.yml`:
  Upstream re-generated the file, while glitch-soc has a specific ignore
  for some file.
  Updated the file as upstream did and kept our extra ignore.
- `config/webpack/shared.js`:
  Upstream added a plugin, but our files are pretty different.
  Added the plugin as well.
- `spec/helpers/application_helper_spec.rb`:
  Upstream refactored tests, but part of them were different because
  of glitch-soc's theming system.
  Applied the refactoring to glitch-soc's change.
