feat(index.html): enhance privacy section with new details

Added a new "Privacy" section to the index page explaining that GoogleDonts does not track users, log data, and maintains separate connections to Google Fonts to protect user information. Additionally, included a link to the open-source repository for transparency. These changes aim to provide users with a clearer understanding of the privacy benefits and the open-source nature of the service.

+        GoogleDonts is a privacy-focused service. It does not track you or log
+        any data. It creates a fully separate connection to Google Fonts for
+        each request, so Google does not see your IP address or any other
+        information about you.
+      </p>
+      <p>
+        The service is open-source and you can view the source code on
