obsstore: update create docstring to point to the coder friendly function The `obsstore` class have a `create` method that create new obsolescence marker from node. There is another function in the same module `createmarkers`. This other function is higher level and automatically missing meta data (ultimately calling the first one) We add a new comment in the docstring of `obsstore.create` highlighting that people writing new code probably want to use the top level one.
