fix: add immediate to payload in useTransition hook

[wyze]

Why

This change does fix #1581. I'm not sure if this is the right change though, given the comment above the code.

What

Add immediate back to the array of default props to allow useTransition({ immediate: true }) to be respected again.

I'm not sure this should be added to default props... if you add immediate: true to the phases it works as intended. If we want it to work when passing in the regular transitionProps then we probably need to include it in payload

react-spring/packages/core/src/hooks/useTransition.tsx

Line 240 in 055eb70

const payload: ControllerUpdate<UnknownProps> = {

Thanks for the direction! I've updated the code and added a test.
