[TASK] Ensure short list syntax is used

With #90002, all occurrences of the `list()` function have been migrated
to the short list syntax. Our php-cs-fixer configuration does however
not check the short list syntax usage, so we have one usage of `list()`
in our codebase again.

This change extends the php-cs-fixer configuration to ensure, that
only the short list syntax is used. The new ruleset has been applied
to the codebase and one usage of the `list()` function has been migrated.
