feat: add valkey instrumentation support (#12060)

**This PR is the work of [AhmadMasry](https://github.com/AhmadMasry)**

Moving from #12003 since we
have issues running certain tests on forked repos.

The Valkey instrumentation is based on the current implementation of the
Redis instrumentation, but keeping into consideration that the two
projects may deviate and lose compatibility, the Valkey instrumentation
is created as a separated module.
