Adding configuration directly under the resource config in a yaml file gives an error

[hafkenscheid]

API Platform version(s) affected: 4.0.17 (symfony)

Description
Adding configuration directly under the resource config (like described in the documentation) does result in an error.

How to reproduce
https://api-platform.com/docs/core/pagination/#disabling-the-pagination-for-a-specific-resource

# api/config/api_platform/resources.yaml
# The YAML syntax is only supported for Symfony
resources:
  App\ApiResource\Book:
    paginationEnabled: false

https://api-platform.com/docs/symfony/security/

# api/config/api_platform/resources.yaml
resources:
  App\Entity\Book:
    security: 'is_granted("ROLE_USER")'

Both result in their corresponding errors:

"paginationEnabled" setting is expected to be null or an array, string given

"security" setting is expected to be null or an array, string given
