Because rc-picker still supports moment.js, but antd uses dayjs, bundler does not contains moment.js.

And cssinjs bundles styles in js, so main.css is reduced, but main.js is increased.

The Antd team will soon optimize the size of the styles generated in cssinjs to reduce the size of js

css bundle size moved to js bundle size.
