plugins/logout: Speed up intro/outro transition
800ms is very long; double the length of a
Kirigami.Units.veryLongDuration. This unit is intended to be used
standalone, i.e. you're not supposed to multiply it by 2 or use a
hardcoded version of it that's multiplied by 2.
Reduce the intro duration to Kirigami.Units.veryLongDuration * 1, and
the outro duration to Kirigami.Units.longDuration * 1.
The result is faster and feels a lot more responsive to me.
These screen recordings aren't great because there are some frame drops, but the bottom line is that with this MR, the fade-in/fade-out transitions of the logout screen are twice as fast.
