Thanks for the PR 😍

How to test these changes in your application

1. Define the SYMFONY_ENDPOINT environment variable:

   # On Unix-like (BSD, Linux and macOS)
   export SYMFONY_ENDPOINT=https://raw.githubusercontent.com/schranz-php-recipes/symfony-recipes-php/flex/pull-144/index.json
   # On Windows
   SET SYMFONY_ENDPOINT=https://raw.githubusercontent.com/schranz-php-recipes/symfony-recipes-php/flex/pull-144/index.json

2. Install the package(s) related to this recipe:

   composer req symfony/flex
   composer req 

3. Don't forget to unset the SYMFONY_ENDPOINT environment variable when done:

   # On Unix-like (BSD, Linux and macOS)
   unset SYMFONY_ENDPOINT
   # On Windows
   SET SYMFONY_ENDPOINT=

Diff between recipe versions

In order to help with the review stage, I'm in charge of computing the diff between the various versions of patched recipes.
I'm going keep this comment up to date with any updates of the attached patch.

We should keep this in sync with symfony which uses 8.1 and 8.2 currently: https://github.com/symfony/recipes/blob/137e34765a384120bc53d16148910f35e5fc9673/.github/workflows/callable-qa.yml#L243-L278

@alexander-schranz I'll remove skeleton ^5 and add skeleton ^7 (I've seen the error on contrib too)

[alexander-schranz]

yes make sense seems like symfony already upgraded to only test against skeleton 6 and 7

[alexander-schranz]

@pocky thx the contrib reuses the same action: https://github.com/schranz-php-recipes/symfony-recipes-php-contrib/blob/main/.github/workflows/qa.yml#L12

I'm running my own Symfony Flex recipes server with custom PHP recipes (https://github.com/mformono/recipes) and your work has been incredibly helpful. Thanks a lot for your time and effort!

[alexander-schranz]

Nice to see that this is also reusable for other cases :)
