This can be broken out into more MRs if needed. Changes include:

* WishlistIntake: API errors are shown to the user ( T369764). For this, the design uses the standard [Message](https://doc.wikimedia.org/codex/latest/components/demos/message.html) component. It is still subject to design review but can be addressed later.
* Fix edit conflict resolution by using the timestamp of when the wish content was fetched.
* DescriptionSection: Fix race condition in loading DescriptionField. This was a bug only discoverable by Selenium!
* [Tag](https://www.mediawiki.org/wiki/Manual:Tags) edits with `community-wishlist`. This will be useful for AbuseFilters and monitoring in general.
  * **IMPORTANT:** You must manually create the `community-wishlist` tag at Special:Tags on your wiki. `npm run setup` will handle the rest.
* DescriptionField: remove some dead code (`syncCallback`)
* WishlistIntake: refactor code out of `handleSubmit()` 
* WishlistIntake: change `getUniquePageTitle()` to start the first duplicate with a suffix of 2 and instead of 1.
* WishlistIntake: move `allowCloseWindow.release()` to be after the edit was successfully made. Without this, one might accidentally close the tab and lose their work after a failed save.
* Fix issue with CI not knowing about credentials.json
* Add a few JSDoc blocks.
