📚 Description

The data-selectable attribute on table rows was not respecting the rowSelectionOptions.enableRowSelection option. When enableRowSelection is defined (e.g., to
conditionally disable selection on certain rows), the attribute should reflect whether each individual row can be selected via row.getCanSelect().

Before: data-selectable only checked for onSelect, onHover, or onContextmenu props
After: data-selectable first checks if enableRowSelection is defined, and if so, uses row.getCanSelect(), otherwise falls back to the original behavior

This fix ensures that rows with disabled selection get data-selectable="false".

Testing: added tests 'data-selectable attribute with rowSelectionOptions.enableRowSelection' and 'data-selectable attribute fallback behavior' to test that the new behavior and old behavior work correctly.
