Add short option -p for prettier output

[AmosOO7]

Describe the enhancement
Add a short -p flag for the existing pretty command so users can invoke it more quickly using a shorthand option.

Use case
Users who frequently use the pretty command will be able to type -p instead of --pretty, making the CLI faster and more convenient to use.

Additional context
The -p flag should behave exactly the same as --pretty and act as an alias rather than a replacement. This ensures backward compatibility while improving developer experience.

I will work on this

I will be closing this isssue as #234 works better for the project as a whole.
