Require Rust-free versions of Breezy
- version 3.3.0 introduces Rust code, which requires rustc versions newer than available in Debian 11
- For some reason, pip does not even try to install setuptools-rust on the CI, even though it's a build dependency of Breezy https://jenkins.softwareheritage.org/blue/organizations/jenkins/DDOC%2Fdev/detail/dev/2497/pipeline
