[Merge] ~lucaskanashiro/ubuntu/+source/rabbitmq-server:relax-elixir-version into ubuntu/+source/rabbitmq-server:ubuntu/devel

[Lucas Kanashiro]

Thanks for the heads-up Dan! I simply backported the patch applied in v3.8.x branch and I'd not expect a regression after checking the upstream changes. However, importing version 3.8.3 from upstream is the best way to go. So I am rejecting this MP in favor of #1878049.
