Prepare UI tests for rust 1.55 (#9637)

* Prepare UI tests for rust 1.54

* Delete wrong_page.stderr

* CI: run with a staging CI image

* Revert "CI: run with a staging CI image"

This reverts commit 66f5b00d14b50fd9d8fbf773f7e884f380697591.

* CI: debug, again

* LOG_TARGET is only used in std

* Remove unnecessary unsafe

* Fixes

* Use correct rustc locally

* FMT

* Compile with benchmarking

* Review feedback

* Some ui tests

* I know...

* Fix wasm tests
