Update BlazorMobile.Build behavior for Blazor WebAssembly 3.2.0 Preview 2

Update BlazorMobile.Build behavior for Blazor WebAssembly 3.2.0 Preview 2.

As the dist folder does not exist anymore with this new version, as seen here:

As a result of this change, the structure of the published output of a Blazor WebAssembly app is now more consistent with other ASP.NET Core apps. A Blazor WebAssembly app is now published to the /bin/Release/netstandard2.1/publish/wwwroot folder (a dist folder is no longer generated). To publish a standalone Blazor WebAssembly app as a static site, copy the contents of the published wwwroot folder to your static site host. If the Blazor WebAssembly app is hosted in an ASP.NET Core app, the client Blazor WebAssembly app is published into the wwwroot folder of the published server app just like any other static web asset.

Some draft search for myself:

Scénario idéal :

• Import des target nécessaire pour que BuildsDependsOn soit défini
• Import des targets nécessaire pour que PublishDependsOn soit défini
• Remplacer BuildsDependsOn par la liste de PublishDependsOn si possible
• Remplacer PublishDependsOn par BuildsDependsOn. La cible précédente étant déjà effectuée l’action ne devrait pas être appelée une seconde fois. Vérifier fonctionnement des scripts Blazor

Done (differently than expected) but done !
