Step link needs an href attribute so that it's keyboard navigable

[mmazanec22]

Overview of the problem

Oruga version: 0.5.9
Vuejs version: 3.2.41
OS/Browser: Pop!_OS/Chrome

Description

The step nav bar is not currently operable via keyboard because the step a tags to not have href attributes.

Steps to reproduce

Set the steps to be clickable, and then try to use the tab key to navigate through the page.

Expected behavior

I would expect the clickable step nav links to have href attributes so that it's keyboard operable, and to be able to set those href attributes. I would also expect the nav to just be a regular ol with some aria markup and not use semantic nav and link elements when the step progress indicator is not interactive.

Actual behavior

The links are clickable when the steps are set to clickable, but the links cannot receive keyboard focus. A step nav with no clickable elements is a semantic nav element with links despite not being interactive at all, which is potentially misleading to screen reader users.

(Edited because I mixed up animated and clickable.)

Can you make a PR?

Maybe its easier to add tabindex="0" and role="button" as needed, to make them accessible by keyboard?
