Update AdditionalResources.tsx

I changed the URL in MDN HTTP Observatory from  link: 'https://observatory.mozilla.org/', to link: 'https://developer.mozilla.org/en-US/observatory', because

MDN HTTP Observatory is launched, and Mozilla Observatory is now deprecated.

Here is the article: https://developer.mozilla.org/en-US/blog/mdn-http-observatory-launch/
