Highlight the open workspace on each monitor

### Feature Description

In the workspaces widget, it would be much better if the open workspace of each monitor was highlighted. As it is now, the workspace of the monitor with the focused window is highlighted on all the widgets on all monitors.

### Use Case

I use DankMaterialShell with sway, and have three monitors with ten workspaces each. I often want to move a window to another monitor's open workspace with a key binding, but I need to see which workspace is open on that monitor to do that.
