fix(ci): fix YAML parse error in Print runner wait time step

The multi-line python3 -c "..." block had unindented Python code that
terminated the YAML block scalar at line 26, causing a preExecutionError
on every CI run since this step was added.

Inline the Python as a one-liner to stay within the YAML block's indentation.
