Temporary require symfony/templating

[ElectricMaxxx]

To avoid installation issues based by a missing dependency in jms/serializer-bundle we should require symfony/translation temporary. JMS will release a fix on master, when Symfony 4.0 will be released.

Created #158 to remove it.

but this bundle does not require jms/serializer-bundle. should we not do this requirements in the resource-rest-bundle which is the one requiring jms serializer? also wtf, why does the serializer depend on symfony/translation?
