dotnet-dump analyze documentation lacks information about dumpheap command

[gabbersepp]

Issue description

In former versions of dotnet-dump analyze I where able to search for types in the heap by typing dumpheap -T xxxxx. I setup a new dotnet project for playing around with diagnostics stuff and used RUN dotnet-install dotnet-dump in the Dockerfile. In the container I tried to analyze a dump. dumpheap -T xxx gave me this error:

System.ArgumentException: Invalid start address: -T

I took a look into the help and saw:

dumpheap <memoryrange>                     Displays a list of all managed objects.

But the official documentation says:

dumpheap | Displays info about the garbage-collected heap and collection statistics about objects.

Can you please fix the documentation and tell me how I can achieve the type filtering with the new version?

A small edit:
It was a partial mistake of mine. The parameter has to be written in lowercase. using dumpheap -type works as expected. Nevertheless seems the documentation not to be in sync with the output of help. But it is rather a small issue now as the dumpheap works as expected. So close this issue if you like.

I did not create a PR as I do not know if the output of help has to be adjusted or the documentation.
