could not run `quit` on child process despite calling `quit`

Hello,

I'm having trouble shutting down the bash shell I've spawned after I'm done.

• Repo/branch: https://github.com/tangle-network/envio-indexer-blueprint/pull/4

I'm shutting down the session using the following and I've tried various combinations of the 3 commands below without luck on this error.

                    println!("Project template ready");
                    session.send_control('c')?;
                    session.send_line("exit")?;
                    session.send_line("quit")?;

And yet my logs show

Project template ready

Start at rexpect-0.6.0/src/session.rs:356 and reproduce the failure from envio_utils::project::tests::test_project_lifecycle using the shown send_control and send_line calls. The report does not specify the expected shutdown behavior or an acceptance condition, so the desired change must be clarified before work can be considered done.
