[Doc]: Exchange step() for stairs() in the Plot types - Basic section

Problem

step() is quite particular and a bit difficult to understand. I assume that most step-like plots come from data where you know the step points and the values in between.

should maybe be both & the difference shown clearly?

difference shown clearly

I don't know how to do that with the minimalistic approach of the plot types. And I assume step is rarely needed (The plot types section only shows a selection of most common (?) plots. I'd be open tomswitch to showing all, but we should be consistent in our selection.

[story645]

to switch to showing all
I thought the plot types gallery was for showing all the plot types, just very briefly

The difference between stair and step is step:len(x)=len(y) and stair:len(x)=len(y)+1 which I think can be made explicit in how the variables are constructed?

step was just originally chosen because that is what's in the cheatsheet. 👍 to change to stairs, and probably change the cheatsheet too?
