Accessibility nav tabs : disabled tabs need to have tabindex set to -1

[Lausselloic]

To prevent keyboard focus, when a tab is disabled, we need to set the tabindex to -1

http://getbootstrap.com/docs/4.0/components/navs/#tabs

Can be done in static mode for the doc, and also could be managed by the plugin.

Maybe also need to use the aria-disabled attribute to inform screen reader.

Please, fix the title. It's not z-index, but tabindex.

oh yes i'm confused

@patrickhlauke Still on this or may I put in a PR? :)

@Varunram: I don't even know if @patrickhlauke saw this; I had assigned it to him back then.

So, just go ahead.

Seems to have been sorted now (though one instance of disabled links that are still focusable/not marked with aria-disabled remained, which will be fixed by #27788).

Closing (and apologies for not actioning this at the time...life got in the way)
