* docs(kubernetes): add initial reference docs
Add a Kubernetes reference section under docs/reference/kubernetes/ covering
gateway setup, OIDC and reverse-proxy authentication, cert-manager PKI, and
Gateway API external access. Update installation.mdx to link to the new setup
page and nest the new folder under the Reference section in index.yml.
* docs(kubernetes): promote Kubernetes to top-level nav and retitle pages
Move docs/reference/kubernetes/ to docs/kubernetes/ so the section appears
as a top-level nav entry rather than nested under Reference. Retitle the
pages to broader, action-oriented names (Managing Certificates, Ingress,
Access Control) and rename the files to match. Update cross-references in
setup.mdx and the installation page.
* docs(nav): revert Reference to folder mode
The Reference section was switched to explicit section/contents to host
the nested Kubernetes subsection. With Kubernetes promoted to a top-level
folder, restore folder-mode auto-detection. Side effect: sandbox-compute-drivers
is picked up again, which was silently absent from the explicit list.
* docs(kubernetes): add OpenShift install page
Mirror the OpenShift install instructions from PR #1240 into the
Kubernetes docs section. Documents the SCC binding for sandbox pods
and the chart overrides required by OpenShift's Security Context
Constraints (disabled PKI init Job, plaintext TLS, cleared fsGroup
and runAsUser).
