fix(shape, xychart): default LinePath strokeLinecap to round

[williaster]

🐛 Bug fix

Title says it all. This is a good default behavior in order to make sure that paths of single data points surrounded by null values are still visible for Line and AreaSeries.

We could also consider setting this as the default in @visx/shape, but that's a very popular package so I worry about changing behavior 🤔

EDIT: going to make this change in @visx/shape as well as @visx/xychart so that all packages / consumers get the fix.

noting that I made the change in @visx/shape, but also still needed to make it in @visx/xychart for the animated components which ultimately use <animated.path />s
