Auto update of doc strings

[dgilford]

This pull request focuses on improving the documentation for several core functions in the codebase by converting their docstrings to the NumPy/SciPy style. This enhances clarity and consistency, making the code easier to understand and maintain, especially for new contributors. No functional changes to the code logic were introduced.

Documentation improvements:

• Updated docstrings for all functions in src/tcpyPI/utilities.py to use the NumPy/SciPy documentation style, including clear sections for Parameters, Returns, and Examples. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]
• Converted docstrings for key scientific computation functions in src/tcpyPI/pi.py (cape, solve_temperature_from_entropy, pi) to the NumPy/SciPy style, improving parameter explanations and return value descriptions. [1] [2] [3]
• Enhanced docstrings for sample dataset functions in run_sample.py to provide detailed parameter and return value documentation in the NumPy/SciPy format. [1] [2]
