Support for Valkey

[ThallesP]

As Redis is changing its license, most people seems to be migrating off from Redis to Valkey, would be possible to add a module for Valkey?

I would be more than happy to make a PR!

Please do 🙂 . For anyone else looking to create a module have a look at https://github.com/testcontainers/community-module-registry.
