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: Pattern.sampleMeasurement()
+---
+
+The `Pattern.sampleMeasurement()` method will _sample_ the pattern which means
+to draft multiple variants of the same pattern, and stack them on
+top of each other.
+
+In this particular case, it will draft 10 variants of the pattern that vary
+the measurement of your choice between 90% and 110% if the value in the settings.
+
+:::tip
+The goal of measurement sampling is to understand the impact of a given measurement on a pattern.
+:::
+
+:::noteThis method is chainable as it returns the Pattern object:::
+
+## Pattern.sampleMeasurement() signature
+
+```js
+Pattern pattern.sampleMeasurement(string measurement)
+```
+
+## Pattern.sampleMeasurement() example
+
+```js
+import { Aaron } from "@freesewing/aaron"
+
+// Load some public test measurements from the FreeSewing backend
+const measurements = (
+  await (
+    await fetch("https://backend3.freesewing.org/curated-sets/1.json")
+  ).json()
+).measurements
+
+const pattern = new Aaron({ measurements })
+
+const svg = pattern.draft().sampleMeasurement('chest')
+```
