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.rotate()
+---
+
+The `Path.rotate()` returns a path that is a rotated copy of this path.
+This method behaves like calling [Point.rotate](/reference/api/point/rotate) on all nodes of this path.
+
+## Signature
+
+```js
+Path path.rotate(number deg, Point rotationOrigin, cloneAttributes = false)
+```
+
+If you pass a truthy value to the cloneAttributes parameter, it will return a deep clone of the
+path, including its attributes. By default, it will return a shallow
+copy, without the attributes.
+
+## Example
+
+
+<Example caption="Example of the Path.rotate() method">
+```js
+({ Point, points, Path, Snippet, paths, snippets, part }) => {
+
+  points.B = new Point(10, 30)
+  points.BCp2 = new Point(40, 20)
+  points.C = new Point(90, 30)
+  points.CCp1 = new Point(50, -30)
+  points.origin = new Point(6, 34)
+  snippets.origin = new Snippet('notch', points.origin)
+
+  paths.example = new Path()
+    .move(points.B)
+    .curve(points.BCp2, points.CCp1, points.C)
+    .setText("FreeSewing rocks", "text-xs fill-note center")
+
+  paths.rotated = paths.example
+    .rotate(180, points.origin, true)
+    .attr("class", "dotted")
+
+  return part
+}
+```
+</Example>
+
+## Notes
+
+The rotated path is a shallow copy.
+It will in other words not inherit the attributes of the original path.
+
+If you want a deep copy, including the attributes, set the third parameter to true:
+
+`Path.rotate(deg, origin, true)`
