[BUGFIX] Add active class to correct element in EXT:workspaces

The tablist inside the element information modal
in the workspaces module did not longer set the
active state on the correct tab item.

This is due to a change in bootstrap 5, since an
active tab is highlighted by setting the `active`
class on the tab item link (`nav-link`) instead of
the tab item (`nav-item`) itself.

This is fixed by adding the `active` class to the
correct element again.
