Better show for numpy array

**Is your feature request related to a problem? Please describe.**
https://github.com/JuliaPy/PythonCall.jl/blob/ad67c0457ce79f13deb0d04a47808824f8ad7921/src/Py.jl#L186 When it shows a python array in vscode inline results. It would only show `Python` when unexpanded because of the line end. Would it be better to show more informative like Julia Array shows `4×4 Matrix{Float64}:` on the first line?

**Describe the solution you'd like**
shows numpy array shape like `4×4 Matrix{Float64}:`
