### Problem description
This PR adds a shortcut link on the Search (Ctrl+F) popup to the more
advanced "Find" view that is normally accessible at the `View > Find`
menu.
### Implementation description
I added a simple `ImGuiExt::IconHyperlink` link to the `draw()` function
of the `PopupFind` class to display the hyperlink. Clicking the link
will open the Find view, bring it into focus and close the current
popup.

### Additional things

populated for now.
