Replace this notice by a description of your feature/bugfix.
This will help reviewers and should be a good start for the documentation.

Additionally (see https://symfony.com/releases):
 - Always add tests and ensure they pass.
 - For new features, provide some code snippets to help understand usage.
 - Features and deprecations must be submitted against branch main.
 - Changelog entry should follow https://symfony.com/doc/current/contributing/code/conventions.html#writing-a-changelog-entry
 - Never break backward compatibility (see https://symfony.com/bc).
-->

While working on the UX's CI, I noticed that we manually handle Yarn cache (2 _longs_ steps).

Instead, we can use `actions/setup-node` and `cache: yarn` to lighten the workflow file and ease the maintenance.
