<!--
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).
-->

Following #1965 and #2060, I was a bit surprised to see ux.symfony.com tests were executed with UX packages coming from `2.x` branch, instead of UX packages from the same PR.

I believe doing this could help us for the future and prevent some regressions.

I've updated the script `.github/build-packages.php` to automatically replaces **all UX packages requires(-dev)** from all significant `composer.json` files from the repo:
