Resolves #5517

There are still some improvement points. But we will work on these separately.

Will you be removing the following:

"Settings": {
"Abp.Mailing.Smtp.Host": "127.0.0.1",
"Abp.Mailing.Smtp.Port": "25",
"Abp.Mailing.Smtp.UserName": "",
"Abp.Mailing.Smtp.Password": "",
"Abp.Mailing.Smtp.Domain": "",
"Abp.Mailing.Smtp.EnableSsl": "false",
"Abp.Mailing.Smtp.UseDefaultCredentials": "true",
"Abp.Mailing.DefaultFromAddress": "noreply@abp.io",
"Abp.Mailing.DefaultFromDisplayName": "ABP application"
}

from the appsettings.json ?

There is a file in the project root called TestStyleBundleContributor.cs - is this use for anything? Should it be called MyProjectNameBundleContributor and contain similar code to the MyProjectNameBundleContributor found in the Blazor project?
