Merge of request #5534 broke the https://reactdatepicker.com/ website

Describe the bug
This merge seems to have broken the website https://reactdatepicker.com/.

Following css error causing it to render as just a blank page:

index-CfSFwDNY.js:49 Uncaught Error: Minified React error #527; visit https://react.dev/errors/527?args[]=19.1.0&args[]=19.0.0 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.
    at hE (index-CfSFwDNY.js:49:32073)
    at pE (index-CfSFwDNY.js:49:34100)
    at index-CfSFwDNY.js:49:34123

This points to following code in minified react:

    var b0 = n.version;
    if (b0 !== "19.0.0")
        throw Error(a(527, b0, "19.0.0"));

Which according to react docs here, would have had full error message of:

Incompatible React versions: The "react" and "react-dom" packages must have the exact same version. Instead got:

• react: 19.1.0
• react-dom: 19.0.0

This lines up with failing github actions https://github.com/Hacker0x01/react-datepicker/actions/runs/14319179590, and looking at the merge diff (#5534), it indeed introduces the version mismatch.

To Reproduce
Go to https://reactdatepicker.com/ and open the console.

The team had since fixed the website, closing this so it does not linger in the queue.
