[bug]: Dark mode theme selector doesn't animate

[mutewinter]

Describe the bug

Due to disableTransitionOnChange from https://github.com/shadcn-ui/ui/blob/main/apps/www/app/layout.tsx#L93, no dark: animations will function.

This means that the classes in ModeToggle aren't actually doing anything: https://github.com/shadcn-ui/ui/blob/main/apps/www/components/mode-toggle.tsx#L22-L23.

Affected component/components

ModeToggle

How to reproduce

Go to https://ui.shadcn.com/docs/dark-mode/next and change the theme. The icon will not animate.
