.NET 5.0 - Docker Repo Name Change

With the release of .NET 5.0 Preview 4, the Docker repositories where 5.0 images are located have been changed to no longer include core in the repo name.

Details

In order to better align with the .NET 5.0 branding, "core" is being dropped from the repository name. See #1765 for details.

Previous Repositories:

• dotnet/core: .NET Core
• dotnet/core/sdk: .NET Core SDK
• dotnet/core/aspnet: ASP.NET Core Runtime
• dotnet/core/runtime: .NET Core Runtime
• dotnet/core/runtime-deps: .NET Core Runtime Dependencies
• dotnet/core/samples: .NET Core Samples
• dotnet/core-nightly: .NET Core (Preview)
• dotnet/core-nightly/sdk: .NET Core SDK (Preview)
• dotnet/core-nightly/aspnet: ASP.NET Core Runtime (Preview)
• dotnet/core-nightly/runtime: .NET Core Runtime (Preview)
• dotnet/core-nightly/runtime-deps: .NET Core Runtime Dependencies (Preview)

New repositories for .NET 5 going forward:

• dotnet
• dotnet/sdk
• dotnet/aspnet
• dotnet/runtime
• dotnet/runtime-deps
• dotnet/samples -> available once .NET 5.0 releases as GA
• dotnet-nightly
• dotnet-nightly/sdk
• dotnet-nightly/aspnet
• dotnet-nightly/runtime
• dotnet-nightly/runtime-deps

.NET 5.0 Preview 4 will be used as a transition period for this repo name change. This means that the 5.0 floating tags in the old repo will be updated to reference the Preview 4 images. For example, the .NET 5.0 runtime image will be tagged with both mcr.microsoft.com/dotnet/core/runtime:5.0 and mcr.microsoft.com/dotnet/runtime:5.0. This tagging strategy will end once Preview 5 is released. At that point, all 5.0 tags using the old repo name will no longer be updated. In addition, all 5.0 floating tags will be removed from the old repo for the GA release of 5.0 in order to avoid accidental usage.
