Bug: resources.limits in small.yaml for Helm produce warnings - values should be quoted

[Jeansen]

What is the bug?

Using https://github.com/grafana/mimir/blob/main/operations/helm/charts/mimir-distributed/small.yaml when installing via Helm gives the following warnings:

W1223 21:38:18.060748 1501775 warnings.go:70] spec.template.spec.containers[0].resources.limits[memory]: fractional byte value "3006477107200m" is invalid, must be an integer

How to reproduce it?

helm install mimir-prod grafana/mimir-distributed -f https://github.com/grafana/mimir/blob/main/operations/helm/charts/mimir-distributed/small.yaml

What did you think would happen?

A clean install without warnings or errors.

What was your environment?

Kubernetes:

Client Version: v1.31.4
Kustomize Version: v5.4.2
Server Version: v1.32.0

Helm:

version.BuildInfo{Version:"v3.16.3", GitCommit:"cfd07493f46efc9debd9cc1b02a0961186df7fdf", GitTreeState:"clean", GoVersion:"go1.22.7"}

Any additional context to share?

The fix is quite easy. All values for resoruces limits and requests need to be quoted, e.g:

alertmanager:
  persistentVolume:
    enabled: true
  replicas: 2
  resources:
    limits:
      memory: "1.4Gi"
    requests:
      cpu: "1"
      memory: "1Gi"
  statefulSet:
    enabled: true

See: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/#example-2

I'd be happy to create a PR with correct values.
