Unpin prometheus library versions from go.mod

[perdasilva]

Description

The transition to go 1.22 and kubernetes 1.30 brought with it a conflict between our prometheus library versions and that of k8s.io/component-base (which we use for its feature package). Until component-base bumps their version of prometheus, we'll need to track it.

Fix

There have been updates to the component-base dependencies already. Once 1.30 is released, we can try to drop the replaces from go.mod
