Telegram for devdojo/auth

Hi there,

I've not used the Telegram Socialite provider before, this is why it is not listed as one of the supported providers in the Auth package. But as far as I can see here in the Telegram Provider.php#L52, the Telegram provider's redirect() method does not return a proper redirect response but instead returns an HTML string. However the redirect() method in the SocialController in the auth package expects to return an Illuminate\Http\RedirectResponse here: src/Http/Controllers/SocialController.php#L18.

Can you try to modify the redirect method in SocialController to handle the Telegram provider specifically:

public function redirect(Request $request, string $driver): RedirectResponse
{
    $this->dynamicallySetSocialProviderCredentials($driver);

    if ($driver === 'telegram') {
        // For Telegram, the redirect method returns HTML, not a proper redirect response
        return response()->make(
            Socialite::driver($driver)->redirect(),
            200,
            ['Content-Type' => 'text/html']
        );
    }

    return Socialite::driver($driver)->redirect();
}

This will properly return the HTML for Telegram's custom login button.

Let me know if it works.
