[FEATURE] Update return type annotations on WorkspaceClient API properties

[themattmorris]

Problem Statement
Type-hinting for return statements on API properties of WorkspaceClient no longer helpful beginning with version 0.42.0.

Though the imports exist at the top of the file for the API names, the return types specify the full path to these objects, which does not play nicely with editor help:

Previous

This sample uses 0.41.0.

Since 0.42.0

(it thinks that w.tables returns Any).

Proposed Solution
Updating the return type hints in the api properties to be as they were before, i.e. specifying the object type they are returning (which are imported in the module) as opposed to the full path to the object.

@tanmay-db Should the Regression label be added here? This was working well previously, it's only the last few versions where this has become an issue
