Add "congratulations" modal when video finishes

[EfficiencyJunky]

When people finish the video, we want them to know they have unlocked some new goodies. So we want to create one more modal to popup and let them know.

1. Congratulations on watching the full video
2. If you had fun, please subscribe to Wolf & Love and share this with a friend
3. New features unlocked

Switch the "info" modal to be the new modal.

Changed "" block to be a "" and used CSS to format accordingly. This makes it possible to copy the text of the website URL by tapping the "tap to copy" button on Mobile</p> </div> </div> <div class="page-bar-simple"> </div> <div class="footer"> <ul class="body"> <li>© <script> document.write(new Date().getFullYear()) </script> Githubissues.</li> <li>Githubissues is a development platform for aggregating issues.</li> </ul> </div> <script src="https://cdn.jsdelivr.net/npm/jquery@3.5.1/dist/jquery.min.js"></script> <script src="/githubissues/assets/js.js"></script> <script src="/githubissues/assets/markdown.js"></script> <script src="https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@11.4.0/build/highlight.min.js"></script> <script src="https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@11.4.0/build/languages/go.min.js"></script> <script> hljs.highlightAll(); </script> </body> </html>
