MDL-81889 tool_generator: add examples to behat steps
The tool_generator creates a testing scenario that can execute
all steps from behat_data_generators (with some limitations),
change admin settings and delete courses and users to cleanup
the created entities. However, this list of valid steps will
change over time and it will be great if all available steps
are listed with examples.
