cache_dir config is enforced

[Nek-]

Hello,

I wanted an idempotent cache but the translator uses the cache dynamically. In Symfony you can redefine the cache_dir in configuration, but this configuration is ignored by this bundle and overrided to the default cache directory.

I used this code as a workaround that will not work with the master branch of the bundle:

class IdempotentCachePass implements CompilerPassInterface
{
    public function process(ContainerBuilder $container): void
    {
        $definition = $container->getDefinition('sylius.theme.translation.translator');
        $defaultOptions = $definition->getArgument(4);
        $defaultOptions['cache_dir'] = $container->getParameter('kernel.tmp_dir');
        $definition->setArgument(4, $defaultOptions);
    }
}
