📝 Add parameter names to code examples in README
@sgugger, @stevhliu and @MKhalusova 

Updated the code examples in the README file to include parameter names for better clarity and readability. Previously, the examples were missing parameter names, which could lead to confusion. By adding the parameter names, it becomes easier for users to understand and utilize the code correctly.

Thanks! 🙌
> Thanks for your PR. I don't believe this makes those basic examples easier to understand, however, so I would leave things as is.

Hi @sgugger, thank you for your feedback. It might be nice to specify the 'model' parameter of the pipeline function. This is how I will update all the tasks in the https://huggingface.co/tasks section.
