Write release notes for 5.0~beta1
On 2022-04-05 we'll release 5.0~beta1, which will the first supported Bullseye-based release (including security support, i.e. after that date, every time we release a new 4.x version that fixes security issues, we'll also release a new 5.0~y).
We'll need a call for testing for this.
