Refactor the GetPage function to check for an empty slice of items
instead of a nil pointer. Update tests to cover cases for nil and
empty slices, ensuring consistent behavior and improved clarity.
Ensure the pagination function correctly handles out-of-bounds indices
when slicing items. Update the slice logic to prevent slice bounds
errors and add a test case for better coverage of edge cases.
Updates the Codecov badge URL in the README to ensure it
correctly points to the project repository. This enhances
documentation clarity and reflects the correct integration
status.
