Drop en-us/ from AI summarization Microsoft Learn URLs

Normalize the canonical Power Pages Learn URL form (no locale prefix) across
the four places that still carried `en-us/` for the AI summarization APIs:

- backend-plan.html (Data Summarization API doc link — last fix kept en-us/
  by mistake)
- agents/ai-webapi-integration.md Sources block (3 URLs)
- skills/add-ai-webapi/references/ai-api-reference.md Sources block (3 URLs)

Other locations were already without the prefix, so they were untouched.
The unrelated /add-server-logic docs and the Copilot Hub admin reference
keep their existing `en-us/` form (out of scope for this fix).
