fix: move @vite/plugin-react to devDependencies

[Ty3uK]

Looks like @vite/plugin-react should be listed in devDependencies.

Here is output from NextJS project:

❯ bun why vite --depth=2
vite@7.3.1
  └─ peer @vitejs/plugin-react@4.7.0 (requires ^4.2.0 || ^5.0.0 || ^6.0.0 || ^7.0.0)
     └─ @effector/reflect@10.0.2 (requires ^4.3.4)
        └─ (deeper dependencies hidden)
