fix #3012: PDFDownloadLinkProps Type Error

[islam-kamel]

Fix #3012
Description:
This pull request addresses the TypeScript error TS2769: No overload matches this call that occurs when using PDFDownloadLink as described in issue #3012.

Changes:

• Updated the type definitions for PDFDownloadLink to correctly accept the child render function.
• Adjusted the implementation to align with the expected types.

Steps to Reproduce:

1. Use PDFDownloadLink with the following setup:

   import { PDFDownloadLink } from '@react-pdf/renderer';
   
   const MyDocument = () => (
     <Document>
       <Page>
         <Text>Hello, world!</Text>
       </Page>
     </Document>
   );
   
   const DownloadLink = () => (
     <PDFDownloadLink document={<MyDocument />} fileName="example.pdf">
       {({ loading }) => (loading ? 'Loading...' : 'Download PDF')}
     </PDFDownloadLink>
   );

2. Run tsc or start the application.
3. Observe the TypeScript error.

Expected Behavior:
The PDFDownloadLink should correctly accept the child render function and render "Loading..." while the document is being prepared or "Download PDF" when ready.
