TL;DR

Vertical nav/step list

• Adds new element span.pf-v6-c-wizard__nav-link-status-icon that is the first thing in .pf-v6-c-wizard__nav-link when there is an error on a step.
  • Technically this element will hold any status icon, but so far we only support error status.
  • We're using the "exclamation circle" icon there since the step numbers are also circles. I think we usually use exclamation triangle, so calling that out.
• Adds span.pf-v6-c-wizard__nav-link-main that wraps everything else in .pf-v6-c-wizard__nav-link (.pf-v6-c-wizard__nav-link-text and .pf-v6-c-wizard__nav-link-toggle)
• When a step has an error, .pf-v6-c-wizard__nav-link getc class .pf-m-danger

Mobile nav toggle

• Adds new element span.pf-v6-c-wizard__toggle-status-icon that is the first thing in .pf-v6-c-wizard__toggle-list-item when the current step in the mobile nav toggle has an error
  • Same notes as the vertical nav notes above
• When the current step has an error, the .pf-v6-c-wizard__toggle-list-item in .pf-v6-c-wizard__toggle gets class .pf-m-danger

Assigned this to myself and bringing this work in as part of the PR that will update the core version all together, since it will also require the core update to work properly.
