⚠ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: composer.lock

Command failed: composer update symfony/event-dispatcher:7.0.2 --with-dependencies --ignore-platform-req='ext-*' --ignore-platform-req='lib-*' --no-ansi --no-interaction --no-scripts --no-autoloader --no-plugins
Loading composer repositories with package information
Dependency symfony/polyfill-php80 is also a root requirement. Package has not been listed as an update argument, so keeping locked at old version. Use --with-all-dependencies (-W) to include root dependencies.
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires symfony/event-dispatcher ^5.0 || ^6.0 || ^7.0 -> satisfiable by symfony/event-dispatcher[v7.0.2].
    - symfony/event-dispatcher v7.0.2 requires php >=8.2 -> your php version (8.1.99; overridden via config.platform, actual: 8.1.27) does not satisfy that requirement.
