Workboard: fix CTRL+click on "Create Task" and "Edit Task"

Summary:
The CTRL+click now opens the links in a new tab, like any other
normal link opened with CTRL+click.

Note that the middle-click was already working.

Closes T15157

Test Plan:
- visit a Workboard
- column > menu > mouse on "Create Task"
    - CTRL+click: open in new tab (→ now works)
    - normal click: open the pop-up (→ still works)
    - middle-click: open in new tab (→ still works)
- column > single Task > mouse on "Edit"
    - CTRL+click: open in new tab (→ now works)
    - normal click: open the pop-up (→ still works)
    - middle-click: open in new tab (→ still works)
