Update Identity package references in Blazor WASM project to the latest 3.1.2 release

[mkArtakMSFT]

When creating an Blazor WASM project with Individual Auth option, the referenced identity packages are 3.1.0. They should instead be the latest 3.1.2 version.
This indicates an issue with the MicrosoftAspNetCoreIdentityEntityFrameworkCorePackageVersion variable value in here:

aspnetcore/src/ProjectTemplates/ComponentsWebAssembly.ProjectTemplates/ComponentsWebAssembly-CSharp.Server.csproj.in

Line 31 in a700aa9

<PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="${MicrosoftAspNetCoreIdentityEntityFrameworkCorePackageVersion}" />
