PHP 8.4: Implicitly nullable parameter declarations deprecated

This issue also happens to be caught by phpcs, so I fixed these issues in a single go

The merge request was not correctly linked to this issue. It is available at https://git.drupalcode.org/project/consumers/-/merge_requests/20

This looks good to me. Thanks.

@eojthebrave Is it possible to tag a new release, so downstream modules that require a stable release for Consumers have a green pipeline again? See for example https://git.drupalcode.org/project/simple_oauth/-/jobs/3848264

Automatically closed - issue fixed for 2 weeks with no activity.

+1 on tagging a new release. PHP 8.4 has been released in November 2024 already.
Attaching a patch for use with Composer..
