Update MAUI tutorial prerequisites and SDK version notes

- Add explicit Copilot+ PC and Windows 11 build 26100 requirement
- Add Developer Mode prerequisite
- Specify Windows App SDK 2.0.0-preview1 (was unversioned)
- Update LanguageModelSkill note: 'current experimental build' -> 'Windows App SDK 2.0 preview'
- Remove 'release/experimental' branch switch (sample on main branch now)

-Complete the steps for .NET MAUI described in the [Get started building an app with Windows AI APIs](get-started.md).
+- **Copilot+ PC** with NPU — required for Phi Silica. See the [Copilot+ PCs developer guide](../npu-devices/index.md).
+- **Windows 11 build 26100 or later** (25H2) — check with `winver`.
+- **Developer Mode** enabled — Windows Settings → System → For developers → Developer Mode.
+- **Visual Studio 2022** with the **Windows application development** workload.
+- **Windows App SDK 2.0.0-preview1** — install via NuGet (`Microsoft.WindowsAppSDK` version `2.0.0-preview1`).

-> The `LanguageModelSkill` enum (`Summarize`, `Rewrite`) is not available in the current experimental build. The examples above use prompt engineering — prepending an instruction to the input text — to achieve the same result. When the Skill API is released, you can replace the prompt construction with `new LanguageModelOptions { Skill = LanguageModelSkill.Summarize }`.
