Fix redirection not handled when downloading .NET Core

What does this MR do?

Replace official asdf plugin for dotnet-core with https://github.com/willmeek/asdf-dotnet-core/tree/add_redirect_to_curl_command. This fixes a bug in which .NET isn't downloaded from MicroSoft servers because its location has changed and curl isn't configured to follow redirections.

To be reverted once https://github.com/emersonsoares/asdf-dotnet-core/pull/27 is merged.
