Storybook fix no longer works because of appType change

[lukereative]

Storybook changed which appType was used in it's vitebuilder to be 'custom' – storybookjs/builder-vite#453 which causes the check within the workaround plugin to not work.

      if (server.config.appType !== 'custom') {

This means that the fonts aren't loading in storybook.

The workaround that I'm using at the moment is putting this in my storybook config:

viteFinal: async (config) => {
    config.appType = 'spa';

  return config;
},

But I don't think that's a long term fix, I think a new check will be needed.
