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.noop()
+---
+
+The `Path.noop()` method adds a placeholder path operation.
+A `noop` operation does nothing, but is intended to be replaced later
+with [`Path.insop()`](/reference/api/path/insop).
+
+## Signature
+
+```js
+Path path.noop(string id)
+```
+
+:::tipThis method is chainable as it returns the `Path` object:::
+
+## Example
+
+<Example caption="Example of the Path.noop() method">
+```js
+({ Point, points, Path, paths, part }) => {
+
+  points.left = new Point(10,10)
+  points.dartLeft = new Point(40, 10)
+  points.dartTip = new Point(50, 50)
+  points.dartRight = new Point(60, 10)
+  points.right = new Point(90, 10)
+
+  paths.withoutDart = new Path()
+    .move(points.left)
+    .line(points.dartLeft)
+    .noop('dart')
+    .line(points.right)
+
+  paths.withDart = paths.withoutDart
+    .clone()
+    .insop(
+      'dart',
+      new Path()
+        .line(points.dartTip)
+        .line(points.dartRight)
+    )
+    .attr('style', 'stroke-width: 2px; stroke-opacity: 0.5; stroke: orange;')
+
+  return part
+}
+```
