Describe the problem

The EuiHorizontalSteps component blocks click events when a step is disabled, but allows the button to take keyboard focus. It would be an improvement if the button had a tabindex="-1" to prevent it from taking keyboard focus either while disabled. Screenshot below. an aria-disabled="true" attribute so screen reader users can hear the button in the tabindex, but also be made aware it's not currently available.
