[Bug]: `winapp init` should ask to install winapp nuget package

[nmetulev]

Describe the bug

winapp ini installs the winapp nuget package for csproj projects without prompting the user first. It should prompt the user if they'd like us to install nuget packages to enable dotnet run work for packaged applications

To Reproduce

1. Create new wpf app dotnet new wpf
2. winapp init via any combination
3. notive the csproj has the nuget packages installed and the user was not asked

Expected behavior

The user should be asked whether they'd like us to install required nuget packages to enable dotnet run for packaged applications

if nuget packages are already installed, should skip this question
