Updated pyroject.toml Formatting

This pull request makes minor updates to the pyproject.toml file, specifically refining the license specification and adjusting the classifiers list.

• Metadata updates:
  • Changed the license field from a table with a text key to a simple string value ("MIT") to better align with standard pyproject.toml conventions.
  • Removed the "License :: OSI Approved :: MIT License" entry from the classifiers list, likely to avoid redundancy with the dedicated license field.
