Revise README formatting and content Added “Usage Example” section to README #13714

[Aujasyarajput18]

Added a new Usage Example section to the README file showing how to clone the repository, run tests, and use the findMedianSortedArrays function in Python.

Reformatted the README for better visual clarity and onboarding―including clearer section headers, emojis for readability, and code block examples.

Ensured that new contributors and learners can easily find instructions to get started and run their own code.
