Update linear_regression.py

[PurvalBhude]

add error handling function. it can handle errors and still run the linear regression algorithm.

Describe your change:

Added try-except blocks for network errors while fetching the dataset (requests.exceptions.RequestException).
Added error handling for gradient descent and sum of square error calculations to avoid crashing during matrix operations.
Ensured that the main function can handle unexpected issues during the linear regression process and print useful debugging messages.

Let me know what exactly you are trying to change or enhance for ??

[PurvalBhude]

i am trying enhancing the code's robustness by adding error handling to prevent crashes during key operations like dataset fetching, gradient descent, and error calculations. Specifically, i am ensuring that network issues, matrix operations, and computational errors don't disrupt the linear regression process, providing useful debugging messages instead.
