Do we want to add this ResourceDetector to the list of entry points here or were you thinking that would be for another PR?

In #3992 we added os resource detector to the list of entry points in the same PR

LGTM -- thanks for doing this. Left a comment about linting.

What should our guidance be for adding in resource detectors that have attributes that are not yet stable in the semantic conventions? Should we be including this as part of the sdk package? I know we might have (mistakenly) added the os resource detector as part of the sdk. Should we place these in contrib for now until sem convs are stable?

I would be good with adding an underscore _ in front of the resource detector to indicate that it is currently in experimental state.
