We can't embed Tweet in doc-builder

Context: For the ML for Games Course I wanted to embed some tweets from Scenario.gg team that made very good showcase of their features.

However, it seems we can't do it with doc-builder since building the PR lead to errors that seems related to the fact that when we embed a tweet, we add a javascript.

`[vite-plugin-svelte] /tmp/tmprl7wke7x/kit/src/routes/unit2/2d-generation/+page.svelte:8:0 A component can only have one instance-level <script> element`

I think it's a low-priority feature but it worth mentioning it.
