Default DotvvmPresenter should not be registered as IDotvvmPresenter

[tomasherceg]

This is just nitpicking and I am not sure if it is even a thing, but we are registering the default DotvvmPresenter as IDotvvmPresenter:
https://github.com/riganti/dotvvm/blob/main/src/Framework/Framework/DependencyInjection/DotVVMServiceCollectionExtensions.cs#L65

I am not sure if someone would implement their own presenter for handling the pages, commands, and static commands. I think we should register it either as DotvvmPresenter (if someone wants to modify it, they'll probably inherit this class anyway). Alternatively, we can let the user specify the default presenter using some other way.

Using IDotvvmPresenter (which is implemented by every presenter) as the service key is confusing, and it breaks everything in case someone accidentally registers the presenter as IDotvvmPresenter without a meaningful error message.
I got reports it happened when someone registered all presenters using Scrutor with AsSelfAndImplementedInterfaces. It is clearly an error, but it is quite difficult to find.
