Does anyone have a working repo of the Storybook for RN?
Unhandled Rejection (Error): Cannot load null or undefined font source: { "percolate": undefined }. Expected asset of type FontSource for fontFamily of name: "percolate"

To Reproduce

1. Follow Storybook for RN tutorial
   https://storybook.js.org/tutorials/intro-to-storybook/react-native/en/get-started/
   Links were out of date for Add Assets here - I found the closest but I think I'm missing some files:
   https://github.com/chromaui/learnstorybook-code/branches/master/src/assets/icon
   https://github.com/google/fonts/trunk/ofl/nunitosans assets/font
2. Ran "yarn web" to start app in browser, "yarn storybook" to run Storybook in browser, got this error:
   ×
   Unhandled Rejection (Error): Cannot load null or undefined font source: { "percolate": undefined }. Expected asset of type FontSource for fontFamily of name: "percolate"
   loadFontInNamespaceAsync$
   C:/Users/erdohert/Repos/src/Font.ts:96
   93 | return await loadFontInNamespaceAsync(fontFamilyOrFontMap, source);
   94 | }
   95 |
   96 | async function loadFontInNamespaceAsync(
   97 | fontFamily: string,
   98 | source?: FontSource | null
   99 | ): Promise {

Closing this in favor of #608 as to have only one place for the changes to the tutorial.
