Move croact from devDependencies to dependencies in croact-css-styled

[wxgisu]

croact is used in an import statement in styled.d.ts file in the croact-css-styled package, but it is included as devDependencies instead of dependencies. This causes vite build and vite dev failures when the package is used in a pnpm monorepo. See detailed explanation in another related pr: daybrush/moveable#1115

Fixing the issue by moving croact from devDependencies to dependencies in the croact-css-styled package.
