p5.strands tutorial: rename the sphere() helper function

[davepagurek]

Topic

When running the code in https://beta.p5js.org/tutorials/intro-to-p5-strands/, there's is a helper function called sphere here:

This leads to some somewhat confusing code, as sphere() is already a thing in p5. Maybe we can rename this to something else?

@davepagurek what about something like "randomPositionOnSphere"? Long but more descriptive and not in conflict

[davepagurek]

That sounds good to me!
