🚀 [Feature] Add Redis Service to Docker Compose Files

[Revisto]

🚀 Feature

Add a Redis service definition to the development (docker-compose.dev.yaml) and production example (docker/docker-compose.yaml) Docker Compose files to simplify setup for development and document the option for production.

So the main benefit is to improve performance?

What type of gains could we expect?

For me, when I was working on emoji reactions, I added new functions to fetch data from IMAP servers and needed to make sure they worked properly with cached data. Without testing with Redis, it would have caused errors in the get_message_parts_content function (which relies on search_bodystructure) when the data came from cache. Having Redis made it possible to test this properly and ensure everything behaves as expected with cached results, without errors.
