New User Redirect with Credentials

[DNoel26]

Hi,

Would you consider adding the following to the /src/routes/callback.js file, under provider.type === 'credentials'?

if (user.isNewUser && pages.newUser) {
    return {
    redirect: `${pages.newUser}${pages.newUser.includes("?") ? "&" : "?"}callbackUrl=${encodeURIComponent(callbackUrl)}`,
    cookies
    };
}

I edited my local package to allow redirection for credentials as I wanted a single place for this, but I figured it should be easy enough to add into the official Next Auth package (unless there's a reason this was avoided)? My edit was just copy and pasted code from the oauth and email provider types.
