Feature request: Tweet Share link on Lesson/quiz completion

Assuming this is the best place to leave ideas if they come up...

Have you thought about adding a "Share your success" button to the end of lessons/quizzes?

This is a simple and effective way of giving users a way to celebrate their wins publicly with their friends whilst also marketing the Academy simultaneously.

This was hugely effective during the Hackathons. See [this Twitter Search](https://twitter.com/search?q=%23d_dminihack&src=typed_query) for the `#d_dminihack` hashtag

It is simple to add this feature whereby we can control/populate what they tweet to ensure it has a specific hashtag, @'s academy/partners/whatever we fancy.

If you click [this link](https://twitter.com/intent/tweet?text=I%20just%20completed%20the%20%22Build%20a%20basic%20NFT%22%20solidity%20course%20on%20%40devdao_Academy%0A%0ACheck%20it%20out%20-%20https%3A//academy.developerdao.com/lessons/projects/2) for example, it generates the tweet below.


Benefits:

1. Give users a way to celebrate their wins with their friends
2. Free social media marketing into their networks (people do what their friends do)
3. Social Signals like this are very good for SEO
