Describe the Bug

Running pnpm astro dev with the <Prism /> component from @astrojs/prism and the Cloudflare Workers integration in the latest beta version of Astro throws the following error:

02:23:31 [ERROR] [vite] Internal server error: require is not defined
      at null.<anonymous> (.../astro-v6-cf-prism/node_modules/.pnpm/prismjs@1.30.0/node_modules/prismjs/components/index.js:1:47)
      at Object.runInlinedModule (workers/runner-worker.js:1314:56)
      at CustomModuleRunner.directRequest (workers/runner-worker.js:1166:80)
      at CustomModuleRunner.cachedRequest (workers/runner-worker.js:1084:73)

What's the expected result?

The component should work without any errors.
