helm: gateway: also listen on IPv6 (grafana#9510)

**What this PR does / why we need it**:

Currently the gateway only listens on IPv4. On IPv6-only clusters, this
causes the readiness probe to fail, rendering the gateway unusable.

Helm: Quote tenantId value in logsInstance (grafana#9486)

**What this PR does / why we need it**: Quotes the value of `tenantId`
for the cases where tenantId is made up of only numerical values (i.e.
if tenantId is `0`)

the motivation for this is that we have long used the tenant id `0` in
our loki instance for some stuff. We probably should fix that, but it's
going to be easier (at least for us) to patch this than to rename this
tenant or migrate to a new tenant.

**Which issue(s) this PR fixes**:
N/A - If you'd like me to file an issue to track this there as well, let
me know and i'll write one up. i figured this fix was simple enough

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

Helm: use $.Release.Namespace consistently (grafana#9330)

Add image reference by digest to Loki Helm chart (grafana#9442)

Adds the ability to reference images by digest instead of tag. Useful
for images that are bundled in an OCI artifact, where the digest must be
used.

**Which issue(s) this PR fixes**:
Fixes grafana#9440
