mongodb: bump mongodb-sharded chart to 9.4.14

[delthas]

Summary

Bump the vendored mongodb-sharded chart from 9.4.4 → 9.4.14 to pick up the upstream pgrep -x liveness-probe fix (bitnami/charts#36488) — the chart-side fix for the mongos/configsvr startup race we hit in production.

Why

The mongos livenessProbe ran pgrep mongos, which substring-matches mongosh. During simultaneous StatefulSet startup, the bitnami entrypoint runs mongosh --host configsvr to wait for the configsvr replica set; that call hangs indefinitely when the configsvr port is open but the replica set hasn't completed primary election. The real mongos never gets execd, the probe stays green (matching the hung mongosh), readiness fails correctly but Kubernetes never restarts the container — the cluster deadlocks.

Upstream PR #36488 adds -x (exact name match) to that probe and consistency-hardens the matching three other probes (mongod on shard-data, shard-arbiter, config-server).

What changes

• solution-base/mongodb/Makefile — CHART_VERSION: 9.4.4 → 9.4.14. Also incidentally fixes a latent Makefile bug from ZENKO-5281: git subtree split/merge require running from the repository toplevel, but make -C solution-base/mongodb runs recipes with cwd at this directory. Resolved by adding cd $(TOPLEVEL) to the subtree commands. The bug was hidden during ZENKO-5281 because the original subtree was bootstrapped via manual git commands at the repo root, not via make vendor-sync.
• solution-base/mongodb/charts/mongodb-sharded/ — git subtree merge --squash of upstream mongodb-sharded/9.4.14. Clean three-way merge against our 11 local-modification commits (no conflicts — upstream's pgrep change is in a region disjoint from our local edits). The squash commit reads:

  Squashed 'solution-base/mongodb/charts/mongodb-sharded/' changes from d2eb70018d..cd87843fdd
  git-subtree-split: cd87843fdd50168708d5acb661e1ab3ce7672a54
  

• solution-base/mongodb/charts/mongodb-sharded/charts/common/ — helm dependency build resolved a newer bitnami/common (2.31.0 → 2.31.4). Minor refinements only.

Verification

• pgrep -x is now in all four probe files (mongos, shard-data, shard-arbiter, config-server).
• Chart.yaml: version: 9.4.14, appVersion: 8.0.13.
• Local mods preserved (custom mongos entrypoint via configmap, configServer.serviceName helper, redirect-logs, etc.).
• helm template renders 20 manifests; helm lint passes.

What does NOT change

• solution-base/deps.yaml — image refs point at ghcr.io/scality/zenko/* from ZENKO-5110, independent of the chart's annotations.images. The image bump (8.0.12 → 8.0.13) in upstream's annotations.images doesn't propagate here; Zenko's deployed images are governed by deps.yaml separately.
• solution-base/build.sh — untouched; the charts/common/ directory layout it relies on is preserved.

Follow-up

Unblocks ARTESCA-17516 (revert the installer-side workaround) once a Zenko build incorporating this lands.

Issue: ZENKO-5276
