fix(readme): update README example to

reflect the correct usage of Pipeline function.

The previous example in the README incorrectly
showed the usage of URL and params with the
Pipeline function.
Updated the example to the correct usage,
simplifying the instantiation of the Pipeline
with a single argument, and ensuring the correct
extraction of information.
