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.sampleOption()
+---
+
+The `Pattern.sampleOption()` 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, the variants it drafts depend
+ on [the type of option](/reference/api/part/config/options/):
+
+- For a Percentage or Degree option, 10 steps will be sampled, between min and max
+- For a Counter or Millimeter option, a maximum of 10 steps will be sampled, between min and max
+- For a Constant numeric option, 10 steps will be sampled between 90% and 110% of the value
+- For a List option, each option in the list will be sampled
+- For a Boolean option, both `false` and `true` will be sampled
+
+:::tip
+The goal of option sampling is to verify the impact of an option on the pattern, and verify that
+its min and max boundaries are correct and its default value is sensible.
+:::
+
+:::noteThis method is chainable as it returns the Pattern object:::

+## Pattern.sampleOption() 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 })
