Remove redundant setFocus call, which actually removes focus.

Under i3wm 4.21.1/Qt 6.4.1, the existing code actually removes keyboard focus
from the newly-activated window. Removing the call to setFocus in these cases
fixes the problem. The call to activateWindow is enough to put keyboard focus on
it.

The documentation for activateWindow implies the same.
