No registry entry for memcached and memcachedExporter in values.yaml file

[bono5150]

The values.yaml script from url: https://github.com/grafana/loki/blob/main/production/helm/loki/values.yaml doesn't contain registry entries for memcached (line 3128) and memcachedExporter (line 3151) configurations.

The global configuration for private registry from line 10 doesn't work in this case :(.

To Reproduce
Export required images to private registry.
Update values.yaml file to point to images from private registry.
Run: helm install --values values.yaml loki grafana/loki -n namespace-name

Expected behavior
The custom values in values.yaml file will allow to install loki on kubernetes cluster for images stored in private registry.

Environment:

• Infrastructure: k3s version v1.31.4+k3s1 (one control plane node, three agent nodes), cilium 1.16.5 BGP only, Xen 8.3 (XCP-ng)
• Deployment: helm singlebinary 3.3.2 version

A clear and concise description of what you expected to happen.
The whole installation procedure should work for images stored in private registry.

Screenshots, Promtail config, or terminal output
If applicable, add any output to help explain your problem.

failed to pull and unpack image "docker.io/registry/memcached:1.6.35-alpine"
failed to pull and unpack image "docker.io/registry/memcached-exporter:v0.15.0"

It doesn't look for images in private registry but call docker.io instead.
Owner: registry

The other images are grabbed from private registry and working fine for singlebinary and microservices installation modes.
