TKE-46: fix delete node pool parameters

[wenjiehs]

Doc Change Report

Source issue: TKE-46

Scope

• Updated src/content/docs/basics/node-pool/04-delete-node-pool.md only.
• Corrected DeleteClusterNodePool examples from singular NodePoolId to array NodePoolIds.
• Added required KeepInstance choice in CLI and Python SDK examples.
• Added retain-vs-release reader guidance and verification wording.

Document Identity

• canonical_doc_path: src/content/docs/basics/node-pool/04-delete-node-pool.md
• operation_id: tke.nodepool.delete

No duplicate operation entry was changed in this PR.

Fact Sources

• Tencent Cloud official API documentation: https://intl.cloud.tencent.com/ind/document/product/457/38779
  • Official page update time: 2026-05-27 13:00:05
  • Adopted because it defines DeleteClusterNodePool request parameters as ClusterId, NodePoolIds.N, and required KeepInstance, and describes KeepInstance=true as retaining instances while removing nodes from the cluster.
• Repository source page: src/content/docs/basics/node-pool/04-delete-node-pool.md
  • Adopted because it is the issue-scoped document containing the incorrect examples.

Static Compile

• git diff --check passed.
• Markdown/code-block language inspection passed for the changed page.
• Command examples were checked against the official API parameter names.
• Python SDK field names were checked against the official API model shape.

• npm run build passed: 184 pages built.
