Add `is_palindrome` method to LinkedList class

[asmit27rai]

What's this PR about?

This PR adds a new method is_palindrome to the LinkedList class to check if a linked list is a palindrome. The method works for all types of linked lists: SinglyLinkedList, DoublyLinkedList, SinglyCircularLinkedList, and DoublyCircularLinkedList.

What changes were made?

1. New Method:

   • Added is_palindrome to the LinkedList class.
   • The method traverses the linked list, stores elements in a temporary array, and checks if the array is equal to its reverse.

2. Tests:

   • Added comprehensive test cases for is_palindrome in the test file.
   • Verified functionality for all linked list types.

Fixes: #656

is_palindrone is applicable to any linear data structure right? So let's add it in linear_data_structures/algorithms.py. Keep the method here and call it in is_palindrone in algorithms.py file. Also implement is_palindrone method in OneDimensionalArray, DynamicOneDimensionalArray.

@czgdp1807 So do you want to keep the method here and also add is_palidrome method in OneDimensionalArray and DynamicOneDimensionalArray. And call them in algorithms.py ?
