Dev mode in docusaurus

[adamyonk]

I think there is some path config issue in dev mode for pagefind.js. I was able to get around it using the following steps:

1. ln -s node_modules/@getcanary/docusaurus-theme-search-pagefind/dist/pagefind.js static/pagefind-dev.js
2. npm run swizzle @getcanary/docusaurus-theme-search-pagefind SearchBar -- --eject
3. In src/theme/SearchBar/index.jsx L13:

   React.useEffect(() => {
     const prod = process.env.NODE_ENV === "production"
     const lib = prod ? `${siteConfig.baseUrl}pagefind/pagefind.js` : `${siteConfig.baseUrl}pagefind-dev.js`
     setPath(lib);
   }, [siteConfig]);

Just wanted to document that in case it can be streamlined in the theme itself!
