• IBX-8434: Added ProviderConfiguratorInterface to allow configuration post-processing fieldtype-richtext#169 added one interface to the Contracts namespace: https://ez-systems-developer-documentation--2439.com.readthedocs.build/en/2439/api/php_api/php_api_reference/classes/Ibexa-Contracts-FieldTypeRichText-Configuration-ProviderConfiguratorInterface.html so every files have been modified to (at least) add it to the left tree.
• Sample from IBX-8356: Deprecated Ibexa\Core\MVC\Symfony\Security\Authentication\AuthenticatorInterface to be replaced with Symfony-based authorization in 5.0 core#387
  • https://doc.ibexa.co/en/latest/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Content.html#method_getFields "Return values" description is missing a word.
  • https://ez-systems-developer-documentation--2439.com.readthedocs.build/en/2439/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Repository-Values-Content-Content.html#method_getFields description is a more complete sentence, the link is working (a full stop/period is still missing but that wasn't the scope of the PR.)
