renderDropZone is not a function in 0.18 canary

[chrisvxd]

When using the RSC render, renderDropZone is not defined. Source.

Steps to reproduce

1. Create new project with create-puck-app
2. Upgrade to 0.18 canary
3. Switch to RSC render
4. Add a component with a DropZone, like this -

import { type Config } from "@measured/puck";

type Props = {
  HeadingBlock: { title: string };
  Test: { title: string };
};

export const config: Config<Props> = {
  components: {
    HeadingBlock: {
      fields: {
        title: { type: "text" },
      },
      defaultProps: {
        title: "Heading",
      },
      render: ({ title }) => (
        <div style={{ padding: 64 }}>
          <h1>{title}</h1>
        </div>
      ),
    },
    Test: {
      fields: {
        title: { type: "text" },
      },
      defaultProps: {
        title: "Heading",
      },
      render: ({ puck: { renderDropZone } }) => {
        return <div>{renderDropZone({ zone: "test" })}</div>;
      },
    },
  },
};

export default config;

## What happened

A type error occurs:

TypeError: renderDropZone is not a function

And then hydration errors occur

What I expected to happen

No errors to occur
