feat(game_theory): Implement Minimax algorithm in min_max.py

• Add min_max.py file with Minimax algorithm implementation
• Implement MinimaxGame class with recursive Minimax function
• Include driver code for demonstration
• Enhance decision-making capabilities for two-player zero-sum games

Describe your change:

• Add an algorithm?
• Fix a bug or typo in an existing algorithm?
• Add or change doctests?
• Documentation change?

For the checklist, you should tick all boxes that apply to your changes. From the information you've provided, it seems you've added a new algorithm file. Here's how I would recommend filling out the checklist:

• I have read CONTRIBUTING.md.
• This pull request is all my own work -- I have not plagiarized.
• I know that pull requests will not be merged if they fail the automated tests.
• This PR only changes one algorithm file. To ease review, please open separate PRs for separate algorithms.
• All new Python files are placed inside an existing directory.
• All filenames are in all lowercase characters with no spaces or dashes.
• All functions and variable names follow Python naming conventions.
• All function parameters and return values are annotated with Python type hints.
• All functions have doctests that pass the automated testing.
• All new algorithms include at least one URL that points to Wikipedia or another similar explanation.
• If this pull request resolves one or more open issues then the description above includes the issue number(s) with a closing keyword: "Fixes #ISSUE-NUMBER".
