feat: expand Kubernetes category with researched platforms

After researching the 9 platforms suggested, added 5 to the Kubernetes &
orchestration category (all planned):
- KubeSphere (OSS, ~17k stars) — Kubernetes platform with app store
- k0rdent (OSS, ~630 stars) — Mirantis multi-cluster management
- Platform9 — SaaS-managed Kubernetes with Helm catalog
- Mirantis Kubernetes Engine — enterprise Kubernetes (ex-Docker EE)
- Giant Swarm — curated managed Kubernetes platform

Excluded as category mismatches: OKDP (a data-engineering stack — Spark/
Airflow/Trino, not an app deploy target) and Wodby (CMS/PHP-first hosting).
Northflank and Qovery already exist as managed-paas (correct, unchanged).
