jms/translation-bundle is EOL

[johanib]

Gateway uses an extra translations bundle on top of the Symfony translations, https://jmsyst.com/bundles/JMSTranslationBundle

This bundle seems to be EOL.
Development seems stagnated. It has a dependency on doctrine/annotations, which is abandoned.

This needs some attention. We can:

• Evaluate why we need this
• Replace with potential replacement https://github.com/php-translation/symfony-bundle
• Keep it in for now and fork it if problems arise

Update:
It's compatible with SF ^7.1 (not 7.0). So for now not an issue.
