Improve error display

[justinrubek]

When using thoenix terraform .., the first action of command is to build a terraformConfiguration, but if this operation fails the error message is simply logged using tracing::error. The information needed is available, but it is mangled into a form that is not user friendly.

This should be displayed nicely.

an example: If there is an error evaluating a flake everything will be put onto a single line as \n is printed literally, like this

➜ thoenix terraform github apply
