Add pagination method and update README.md

- Introduced `GetAllPagingAsync` method in `IYourEntityService` for flexible pagination options.
- Updated `YourEntityService` to implement the new pagination method and simplified `GetPaginatedAsync`.
- Added a "Contributing" section to `README.md` to encourage community contributions.
