Upgrade eslint-plugin-perfectionist to version 4.2.0

This requires two changes on our side:

- The order of exports in `web/viewer{-geckoview}.js` changes slightly
  because `eslint-plugin-perfectionist` aligned the sorting order with
  the `eslint-plugin-sort-experts` plugin we used before. This restores
  the change from commit 347f155.
- The `eslint-plugin-import` plugin contains a bug that causes the new
  version of `eslint-plugin-perfectionist` to be reported as unresolved.
  This issue is tracked upstream, and since the plugin works fine we
  can simply extend the ignore list we already have to avoid this error
  until the upstream bug is fixed.
