[EuiSelectableTemplateSitewide] Allow default a link behavior for results about eui HOT 3 OPEN

Hey Rachel! Real quick, can we get a priority level from you/your team on this and when you'd want this by?

There are accessibility concerns here (the option roles that selectable items naturally come with, that might clash with link/<a> tags) that we'd need to loop @1Copenut in on, which would take a little while as he's out on PTO right now.

In the interim, I think elastic/kibana#147710 is resolvable without needing native <a> link rendering - you simply need to detect ctrl/cmd keypress in the click event (see #5408 (comment)).

The pickle with window.open() is that we want to use Kibana's navigateToUrl() function that prevents full reloads of Kibana to make it a better user experience.

This sentence doesn't make sense to me, I'm sorry. A new page/tab will always cause a full load of Kibana in any case, that's straight up how they work. Default link behavior wouldn't change this. window.open() is frankly as close to browser-level new tab behavior as it gets. Can you clarify exactly why this wouldn't work for you all?
