EES-5912 Prevent screenreader announcing unavailable after button click

[Guy-HiveIT]

Don't set aria-disabled to true during 'double click prevention' phase, as this causes screen readers to announce 'unavailable' immediately on button click.
aria-disabled can still be passed in as a prop, as well as disabled

Simple and effective

There's a bunch of tests failing, here's just one example

FAIL src/components/__tests__/ModalConfirm.test.tsx
// ...
expect(
src/explore-education-statistics-common test:ci:       34 |         screen.getByRole('button', { name: 'Confirm' }),
src/explore-education-statistics-common test:ci:     > 35 |       ).toBeAriaDisabled();

Failing tests need investigating
