vulkan gitlab CI failing with wrong rustc version

[oddhack]

See any of the recent ash-compile steps in gitlab internal CI - they all are failing with

error: package ash v0.37.0+1.3.271 (/builds/vulkan/vulkan/ash) cannot be built because it requires rustc 1.69.0 or newer, while the currently active rustc version is 1.68.0

Probably because the Docker image containing rust is now out of date with the underlying project? If so I think you could regenerate and push https://github.com/KhronosGroup/DockerContainers/blob/main/rust.Dockerfile, then just need to update the container SHA256 in gitlab and perhaps github CI scripts.

Correct, we recently bumped our MSRV to #746, and the current CI image predates that release.
