feat(discover): Open in discover from issues page doesn't apply sort (#95679)

When on an issue and the user clicks "View More Events", they're
presented with an "Open in Discover" button. That button currently
doesn't persist the sort param, so I've added it in this PR.

If there is a query param that overrides the default sort, use that.
Otherwise, use `-timestamp` which is what the default sort is for the
issue events.
