Description
Please add the `outline` parameter for LineChartBarData.
It should have `strokeWidth` and `strokeColor` properties.
So I want be able to draw such a line

(Sorry for my exceptional drawing skills)
And maybe also separate `outlineAbove: true, outlineBelow: true`, and `capEnds: false`
Contributor guide
Research direction
Start by locating LineChartBarData and the existing line-rendering code. Clarify how outline, strokeWidth, strokeColor, outlineAbove, outlineBelow, and capEnds should interact, then define tests for the requested drawing behavior. Done means LineChartBarData supports the agreed outline options and renders the illustrated line consistently.
