Implicit dependency on plugins extended by external Day.js versions

[1o1w1]

Issue

Picker props depend on an external Day.js instance, creating an implicit dependency on its plugins. This breaks when the app uses a different Day.js version.

It's very easy for multiple versions of Day.js to coexist in a single project. For example, see this commit: simply adding a latest Day.js dependency to my-component results in two different Day.js versions being present in the project.

In my actual project, the issue was even more subtle—merely updating a component that depends on Day.js inadvertently introduced a second Day.js version.

Reproduction Issue

1. Clone the repository:
   git clone git@github.com:1o1w1/reproduction-rc-picker.git
2. Install dependencies:
   pnpm install
3. Start the component dev server:
   cd packages/my-component && npm run dev
4. Start the application dev server:
   cd packages/my-app && npm run dev
5. Open http://localhost:3000/ in your browser.
6. Click the RangePicker — the app crashes.
