[Bug][a11y]: Table selected row state without "selects" specified lacks sufficient contrast

### Code of conduct

- [X] I agree to follow this project's code of conduct.

### Impacted component(s)

Table

### Expected behavior

It should be possible to distinguish a selected row from a not selected row even when the selection checkbox is not present.

See React-Spectrum for a positive example: https://react-spectrum.adobe.com/react-spectrum/TableView.html#highlight-selection

### Actual behavior

Selected row state with not `selects` attribute specified lacks sufficient contrast to distinguish selected rows from not selected rows, which is a failure of [WCAG 2.1 Success Criterion 1.4.11 Non-text Contrast](https://www.w3.org/TR/WCAG21/#non-text-contrast)
