Resource properties configuration in YAML doesn't work

[maxtorete]

API Platform version(s) affected: 3.1.0

Description
I tried to set the openapiContext property in a Yaml file, but it doesn't work. It woks fine in XML, even if I set the resource in a YAML file and the properties in XML.

How to reproduce
Try this conf from docs:

properties:
    App\Entity\Product:
        timestamp:
            attributes:
                openapiContext:
                    type: string
                    format: date-time

Property's openapiContext configuration is ignored. And then try the same configuration but in XML format, also taken from docs:

<?xml version="1.0" encoding="UTF-8" ?>
<!-- api/config/api_platform/properties.xml -->

<properties xmlns="https://api-platform.com/schema/metadata/properties-3.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="https://api-platform.com/schema/metadata/properties-3.0
           https://api-platform.com/schema/metadata/properties-3.0.xsd">
    <property resource="App\Entity\Product" name="timestamp">
        <openapiContext>
            <values>
                <value name="type">string</value>
                <value name="format">date-time</value>
            </values>
        </openapiContext>
    </property>
</properties>

And this one works just fine. Resource shows the date-time format for timestamp property in SwaggerUI.

PS: I also tried removing the attributes key as I don't see it on YamlPropertyExtractor, but it doesn't work either.

I debugged the code so I think the problem is in this service definition:

<service id="api_platform.metadata.property.metadata_factory" alias="api_platform.metadata.property.metadata_factory.xml" />

I tried to override the alias to api_platform.metadata.property.metadata_factory.yaml instead, but I got some circular reference errors.

So I made some nasty checks, changing api_platform.metadata.property.metadata_factory.xml definition from:

        <service id="api_platform.metadata.property.metadata_factory.xml" class="ApiPlatform\Metadata\Property\Factory\ExtractorPropertyMetadataFactory" public="false">
            <argument type="service" id="api_platform.metadata.property_extractor.xml" />
        </service>

To:

        <service id="api_platform.metadata.property.metadata_factory.xml" class="ApiPlatform\Metadata\Property\Factory\ExtractorPropertyMetadataFactory" public="false">
            <argument type="service" id="api_platform.metadata.property_extractor.yaml" />
        </service>

And then it reads the properties definition in the YAML file.
