Obviously, you'll need to open VSCode.
Show the [bottom] panel by navigating to View > Appearance > Show Panel.
From the right sidebar, drag the search icon into the header area of the bottom panel. A

As you can see the search pane is now at the bottom of the VS Code window, where it will stay until the devs decide to change this again. If that happens, I'll update this guide—so feel free to bookmark or favorite it.
