[Discover][Traces] All "Open in Discover" links now open in a new Discover Tab on left-click (elastic#251103)

## Summary

Closes elastic#241280

Now that we have Discover Tabs, all links from Discover within Discover
should open in a new tab.
This PR updates all the "Open in Discover" buttons to follow that
pattern, as decided by the product team.

- On left-click: it will open a new Discover tab.
- On right-click: users can select to 'open new tab' in their browser.
