refactor: Update disabledClasses in FwbPagination.vue

The disabledClasses variable in FwbPagination.vue has been updated to use the "disabled:opacity-50 disabled:cursor-not-allowed" classes instead of the previous "bg-gray-100 text-gray-700 dark:bg-gray-700 dark:text-white cursor-not-allowed" classes. This change improves the consistency and readability of the code.
