upgrade vagrant to bullseye (#5)

I tested upgrading from buster to bullseye on vagrant, privatebin works fine. It needs a little trick: you have to remove the `local` folder in `/var/www/lufi` (see [this](https://framagit.org/fiat-tux/hat-softwares/lufi/-/issues/194)) and play the role again. Then it works fine. I'm wondering if I should add a task that removes that `local` folder?
