I would vote for using a static page again. However, it does not need and might should not be made using the same software as the current website (Jekyll) as we’ve noted that it not quite the best software coming to internationalization (although @hans and @uniqx are currently working on this).
Going the Python way, there’s Pelican and Lektor, with the latter soon being used by Tor and calling itself “Multilingual” (We can speak multiple languages and allow you to easily create localized websites.). Another popular option seems to be Hugo, a framework calling itself “The world’s fastest framework for building websites” and being used by at least Transportr, run by a F-Droid core member. It might also get used by Briar in future.
Whatever we choose, I would deploy it using GitLab CI/GitLab pages, given the fact that we soon have our own CI runners.
