Experiment: try to run interactive tests with Alacritty

[39555]

WIP. I've connected expectrl to the Alacritty terminal. It can run any command with reedline backend, for example the test run_pipeline_interactively, but the command output is somehow messed up with OSC sequences and prompts, so precise control how it is done in Session::exec_output("jobs") is not possible for now
