Docstring tooltips over parameters not displaying for packages which use Python stubs

[pfbuxton]

Adding "python.analysis.supportRestructuredText": true partially fixes the docstrings (as described in #2251)

For local packages, tooltips over parameters are working for Sphinx formatting style:

and for NumPy/SciPy formatting style:

However, with compiled code, which use *.pyi files for the docstrings the hover does not work, here is an example:

Hovering over linspace we see that the "Parameters" have been correctly formatted:

I find these type of features particularly useful. As there is a lot of important information, even in a simple package like np.linspace, or knowing that height should be in centimetre as in my example.

Trigger Parameter Hints will show them. Hover tips just haven't been implemented yet for parameters.
