fix(packaging): update rulesStorageDirectory to /var/lib/loki/rules in operator (#7748)

#7748

The Loki Operator defaulted to /tmp/rules for rule storage — a non-persistent path that loses data on pod restart. Production deployments using the official Helm chart expect /var/lib/loki/rules.

• Only modifies operator/internal/manifests/var.go
• Sets persistent default storage paths:

  walDirectory          = "/var/lib/loki/wal"
  dataDirectory         = "/var/lib/loki"
  rulesStorageDirectory = "/var/lib/loki/rules"

I will probably take a look at this next week. Currently I'm a bit confused on what it tries to do, the linked issue seems to indicate a bit of a misunderstanding, but we'll get to the bottom of this.

General note: If the PR should fix something that is related to the operator then the changes should be limited to the operator/ directory.

Thank you for the feedback! The PR now touches only operator/internal/manifests/var.go .
Verified with Kind: loki-ruler mounts /var/lib/loki/rules by default.
