Link the dated spec revision, not /draft

Browse source 
The surrounding sentence names 2026-07-28 as the revision that first allows
an array-rooted schema, but the link pointed at /draft, which moves on to
the next revision and stops matching the claim.

## Structured content
Both tools declare an `output_schema` and return `structured_content`. `get_forecast` returns an object; `get_alerts` returns a top-level JSON array, which protocol revision `2026-07-28` is the first to allow — see [Structured Content](https://modelcontextprotocol.io/specification/draft/server/tools#structured-content) in the spec.

Declaring `type:` at the root of an `output_schema` is what makes the array case work. The SDK applies a `type: "object"` default only when the schema declares no root keyword, so `output_schema(type: "array", items: {...})` is taken as written.
