Create Valkey Integration

### Problem Statement

[Valkey](https://valkey.io/) is an open-source fork of Redis. We have an integration for Redis, but not for Valkey yet.

### Solution Brainstorm

Consider creating an integration for Valkey with the same features as our Redis integration.

From @antonpirker:

> We should start with an errors only version of the integration. The tracing/performance instrumentation should be created directly as an OpenTelementry instrumentation, that can be then used by the Sentry SDK.
