helm: release a new helm charts to use k8s service for discover query…

…-scheduler replicas (grafana#9477)

**What this PR does / why we need it**:
Currently, we have a bug in our code when running Loki in SSD mode and
using the ring for query-scheduler discovery. It causes queries to not
be distributed to all the available read pods. I have explained the
issue in detail in [the PR which fixes the
code](grafana#9471).

Since this bug causes a major query performance impact and code release
might take time, in this PR we are doing a new helm release which fixes
the issue by using the k8s service for discovering `query-scheduler`
replicas.

**Which issue(s) this PR fixes**:
Fixes grafana#9195
