Idea: Show the shape of the numpy array in the variable inspector

[javielas]

I have recently started using marimo and I really like it!. One thing that I noticed that would be a nice feature is to add shape information to the numpy arrays in the variable inspector, it is a feature that I really miss from Matlab. Showing the shape for me is far more important than showing the first values, it would save me tons of cells executing x.shape() to then delete it.

Since numpy arrays are multidimensional I propose something like:

ndim: x; shape: (y1, y2,y3,...)

Showing up to the first three dimensions.
