chore: Port FreeSewing.dev to docusaurus

The replaces the NextJS site powering FreeSewing.dev with a Docusaurus
setup. It's part of my efforts to simplify FreeSewing's setup so we can
focus on our core value proposition.

+title: Path.curve()
+---
+
+The `Path.curve()` method draws a cubic Bézier curve from the current position
+via two control points to a given endpoint.
+
+## Signature
+
+```js
+Path path.curve(Point cp1, Point cp2, Point to)
+```
+
+:::tipThis method is chainable as it returns the `Path` object:::
+
+## Example
+
+<Example caption="Example of the Path.curve() method">
+```js
+({ Point, points, Path, paths, part }) => {
+
+  points.from = new Point(10, 20)
+  points.cp1 = new Point(40, 0)
+  points.cp2 = new Point(60, 40)
+  points.to = new Point(90, 20)
+
+  paths.line = new Path()
+    .move(points.from)
+    .curve(points.cp1, points.cp2, points.to)
+    .setText("Path.curve()", "text-sm center fill-note")
+
+  return part
