GraphQL non-existent services issue.

[durimjusaj]

API Platform version(s) affected: 3.2

Description
GraphQL resolver services can not be found if kernel.debug is false.

How to reproduce
I have services that decorates api_platform.graphql.resolver.stage.write, also another service which decorates api_platform.graphql.resolver.factory.item and this service needs api_platform.graphql.resolver.stage.read argument.

Both api_platform.graphql.resolver.stage.write and api_platform.graphql.resolver.stage.read are throwing error for non-existent service when I try to install api-platform/core@3.2.

I can see both services are moved to /config/legacy/graphql.xml, which is loaded only if kernel.debug is true in ApiPlatformExtension.php line 586.
