Added python toolkit to CLI init command

[srikanthbachala20]

This pull request adds support for a new "python" toolkit option in the model initialization CLI, allowing users to initialize models using a Python-based template. The implementation includes updating the available toolkit choices, help text, and logic for selecting the correct repository branch for the "python" toolkit.

Toolkit support and CLI enhancements:

• Added "python" to the list of supported toolkits in the --toolkit CLI option and updated the help text in model() and init() to reflect this new option. [1] [2]
• Updated the logic in the init() function to select the correct GitHub repository branch (DEFAULT_PYTHON_MODEL_REPO_BRANCH) when the "python" toolkit is chosen.

Repository branch configuration:

• Introduced the DEFAULT_PYTHON_MODEL_REPO_BRANCH constant in constants.py to specify the branch used for the "python" toolkit.
• Imported the new constant into model.py for use in the initialization logic.
