[Feature]: Add Valkey Testcontainers

[ThomasVitale]

Module

None

Problem

Testcontainers Java doesn't currently include a Valkey module, whereas their Go and NodeJS counterparts do.

https://testcontainers.com/modules/valkey/

Solution

It would be great to add a Valkey module to Java as well.

Benefit

Feature parity between Java and Go/NodeJS when it comes to Valkey integrations. Especially useful when working on polyglot projects including applications implemented with different languages. Using the same Testcontainers approach across language stacks offers a consistent strategy.

Alternatives

The alternative would be to use GenericContainer in Java while using the ValkeyContainer in Go/NodeJS.

Would you like to help contributing this feature?

Hi, I would like to work on this. @ThomasVitale can you assign me for this?

[ThomasVitale]

Hey @BanulaKumarage, thanks for volunteering for this! I'm not a maintainer for this project, so I cannot handle the assignment.

Hey @ThomasVitale, @BanulaKumarage

I've proposed a PR which supports most features available in the Rust, Go and Node implementations.
