I have now created binary .deb files for Raspberry Pi OS (Bullseye) released on 2022-04-04. and currently downloadable via Raspberry Pi OS – Raspberry Pi
There are versions for both the 32 bit and 64 bit OS. Hopefully @samaaron will post them soon for download on sonic-pi.net website.
EDIT
The 32 bit version is now on sonic-pi.net and both versions can be downloaded from github
