fix: Making binary tree traversals lazy using generators

[dev-soni-07]

Contribution Overview:

• Created a new Python file minimum_platforms.py containing the Minimum Number of Platforms algorithm.
• Included Python type hints for function parameters and return values.
• Ensured the code adheres to the project's coding style and follows PEP 8 guidelines.
• Ran doctests locally to verify correctness.

Additional Details:

• The Minimum Number of Platforms algorithm is a fundamental problem in logistics and transportation scheduling.
• The algorithm calculates the minimum number of platforms required to avoid delays and congestion in transportation systems.
• Properly formatted the code using black for readability.
• Included doctests to illustrate and verify the algorithm's correctness.
• Tested locally using Python 3.11+ and mypy for type checking.

Related Issues:

• Fixes Feature: Addition of Minimum Number of Platforms (Greedy Algorithm) #9119

Checklist:

• Created the new file minimum_platforms.py.
• Included Python type hints for function parameters and return values.
• Formatted the code using black.
• Ran doctests locally to verify correctness.

I'm excited to contribute to TheAlgorithms/Python and would appreciate your review and feedback. Please let me know if any further improvements are needed. Thank you!
