Fix unpackaged app debugging issue report at #406 - StorageFile.GetFileFromApplicationUriAsync doesn't support in unpackaged app (#407)

* Fix StorageFile cannot load in Unpackaged App situation.

* Rename the pub file, given we don't add 10 as part of win10 already in any latest sample, moreover build warning show cannot find the win-arm64.xml given the csproj define the name without 10 as well.

* Update Readme.md to mention how to build or  dotnet run as unpackaged app as example.

* Remove the nuget.config given we don't need it, and we cannot point to public nuget feed.

+## Special Considerations for Debugging as an Unpackaged App in Visual Studio
+
+- This project is not designed to be fully functional in an unpackaged app. However, Windows Copilot Runtime does support unpackaged app.
+- To enable proper startup as an unpackaged app, you need to bootstrap the Windows App SDK either Programmatically or By adding the following configuration to the `.csproj` file during the build process:
+ ```xml
+  <WindowsAppSdkBootstrapInitialize>true</WindowsAppSdkBootstrapInitialize>
+ ```
+- Alternatively, if you are using the Developer Command Prompt for Visual Studio, you can run the app as an ARM64 version using the following command, with the bootstrap property provided:
+```powershell
+dotnet run -p:Configuration=Debug -p:Platform=ARM64 -p:WindowsPackageType=None -p:WindowsAppSdkBootstrapInitialize=true
+```
