Document how to use createdump on native AOT apps

[LakshanF]

In .NET 8, using createdump for native AOT applications require some manual steps:

• Need the C++ runtime
• Need access to the 8.0 .NET core version of createdump. The .NET core version of createdump was modified to work with native AOT applications.

This issue tracks to give the appropriate information for the relevant folks (for example, container steps) so that they can successfully deploy createdump to generate dumps for their application. The main diagnostic document (currently on dotnet/docs#36626, Production Debugging section) needs to be updated with information as well.
