Move QUASI_TYPE_REV to the revision that retries a fetch The image asks raw.githubusercontent.com for the pinned bases four times per build - two slots here, one more in shop's build script - and that is enough to be rate-limited. `build/check-rust-stage.sh` failed on a 429 from the licence fetch with the bytes one second away, so quasi-type's fetch now retries. It bounds the damage rather than fixing the cause. The cause is four fetches leaving the machine at all, and the answer is a mirror on infrastructure we own, which is the same conversation as ebf30337 (the Fedora base images) and is filed as 3d41d15a.
