The help command should show example values for the missing parameters #174
Description
I see the need for examples to understand which values should be used, and they should guide users who want to create only a sample for testing.
Looking to the future, these examples could help AI agents use the seed4j CLI tool.
In theory, these examples should come from the seed4j module definitions, because they will become outdated quickly if they are defined in the CLI, and this could lead to mismatched examples when the CLI allows the use of seed4j extensions.
