Fixes a typo in the internal struct name RaingState → RaitingState in crates/ui/src/rating.rs.

Description

Renamed the misspelled private struct RaingState to RaitingState (two occurrences: struct definition and instantiation site).

N/A — internal rename, no visual change.

@copilot Your are missed to change story, docs?

RaingState is a private internal struct only referenced within rating.rs — it doesn't appear in the story (rating_story.rs) or docs (website/docs/components/rating.md, website/zh-CN/docs/components/rating.md). The two occurrences in rating.rs (struct definition + instantiation) have both been renamed to RaitingState. No other files need updating.
