Create a new documentation page elaborating on various Data Protection error messages

The remaining work in #22029 is to create a new doc page explaining the [error messages](https://github.com/dotnet/aspnetcore/issues/22029#issuecomment-1699772926) containing the link https://aka.ms/aspnet/dataprotectionwarning. Once that's done, we can update the aka.ms link to point to the new, more specific documentation.
