Andrea Fercia ffedf3d752 Accessibility: Widgets: Make the "Available Widgets" section operable with a keyboard.
For a number of years, the "Available Widgets" section has been off-limits for
keyboard users. Now it can be used also with the keyboard. This change introduces
also some improvements for assistive technologies.

- makes the widget toggles focusable and adds an `aria-expanded` attribute to indicate their state
- improves the toggles labelling to clarify context (add/edit)
- changes the controls to choose a sidebar from list items to buttons
- adds an `aria-label` attribute to the buttons to clarify their purpose
- adds an `aria-pressed` attribute to the buttons to indicate which one is selected
- improves color contrast of the selected button
- uses a `wp.a11y.speak()` message to announce to screen reader users when a widget has been added to a sidebar
- moves focus back to the toggle button when closing a widget

See #40677.
