enable_introspection not working with env variable

[medhki]

using an env variable to disable/enable introspection is not woking as should be

overblog_graphql:
    security:
        query_max_depth: 20
        enable_introspection: '%env(bool:GRAPHQL_ENABLE_INTROSPECTION)%'

the issue is related to the set setSecurity method in the OverblogGraphqlExtension.

private function setSecurity(array $config, ContainerBuilder $container): void
{
    $executorDefinition = $container->getDefinition(Executor::class);
    if ($config['security']['enable_introspection']) {
        $executorDefinition->addMethodCall('enableIntrospectionQuery');
    } else {
        $executorDefinition->addMethodCall('disableIntrospectionQuery');
    }

    foreach ($config['security'] as $key => $value) {
        $container->setParameter(sprintf('%s.%s', $this->getAlias(), $key), $value);
    }
}

at compile time the $config['security']['enable_introspection'] is a placeholder like
env_53efa566b94c30e2_bool_GRAPHQL_ENABLE_INTROSPECTION_7b26115e46b824a8dd0e86467640739b
which will always evaluates to true
