[EuiTour] Built-in 'Next' button

[thompsongl]

Would it be possible to have default Next behaviour added to the bottom of the tour steps? Right now I have to pass a custom footer action to each step except the final one, which is a bit clunky - I understand that, in the examples included in the documentation, the tour steps progress via actions such as copy pasting and clicking other buttons rather than clicking Next; however, I think that a Next button would, at the very least, be a common use case worth considering. Here is an example of what we had in our original tour for what was considered the 'default' footerAction:

<EuiFlexGroup responsive={false} gutterSize="s" alignItems="center">
  <EuiFlexItem grow={false}>
    <EuiButtonEmpty color="text" size="xs" onClick={actions.finishTour()}>
      Skip tour
    </EuiButtonEmpty>
  </EuiFlexItem>
  <EuiFlexItem grow={false}>
    <EuiButton size="s" color="success" onClick={actions.incrementStep()}>
      Next
    </EuiButton>
  </EuiFlexItem>
</EuiFlexGroup>

Which rendered to this:

Security Solution is interested in this as well. We'd like to have some built-in previous/next buttons in the tour steps that would allow the user to navigate between the steps.

So far we had to add our custom buttons to the content of every step: elastic/kibana#128405

I think this would still be a valuable addition 👍

It was fixed by #6384. We just added support to pass an array of buttons to footerAction.
