docs: clarify ORT_TELEMETRY_DISABLED disables non-essential telemetry

Note that the variable disables non-essential telemetry and, unlike in ONNX
Runtime, applies on every desktop platform including Windows (GenAI uses 1DS
everywhere, not ETW).

@@ -31,7 +31,7 @@ Telemetry can be disabled in any of these ways:
 
 - **Don't build it in.** Telemetry is only compiled when configuring with `--use_telemetry` (`-DENABLE_TELEMETRY=ON`). To produce a binary that collects no data, invoke `build.py` directly without `--use_telemetry` (the `build.py` driver does not add the flag itself — only the `build.sh` / `build.bat` convenience scripts do).
 - **Automatically in CI / build pipelines.** When a well-known CI environment variable (`CI`, `TF_BUILD`, `GITHUB_ACTIONS`, `GITLAB_CI`, and others) is set to a truthy value, GenAI suppresses all telemetry — the 1DS uploader is never created and no device identifier is written. This matches ONNX Runtime, Olive, and Foundry Local.
-- **At runtime, via environment variable.** Set `ORT_TELEMETRY_DISABLED=1` (also accepts `true` / `yes` / `on` / `y`, case-insensitive) before the library initializes. This is the same variable honored by ONNX Runtime.
