When the code lived in dotnet/templating, the 1.x, 2.0, and 2.1 templates all needed to sit side-by-side.
Now that this code builds from aspnet/templating, we're reorganizing the folder and branch structure to
match the aspnetcore runtime repos.
Branches:
rel/1.1.5 = Microsoft.DotNet.Web.ProjectTemplates.1.x
rel/2.0.3 = Microsoft.DotNet.Web.ProjectTemplates.2.0
dev = Microsoft.DotNet.Web.ProjectTemplates.2.1
