* Prepare for rust stable 1.59 Besides preparing the UI tests this also adds a new script update-rust-stable.sh script for simplifying the update of a rust stable version. This script will run all UI tests for the new rust stable version and updating the expected output. * Ensure we run the UI tests in CI * use staging ci image * More test updates * Unignore test (#11097) * empty commit for pipeline rerun * empty commit for pipeline rerun * Try to make clippy happy * More clippy fixes * FMT * ci image production Co-authored-by: alvicsam <alvicsam@gmail.com> Co-authored-by: Alexander Samusev <41779041+alvicsam@users.noreply.github.com>
