Error with dropdown fields on php8

Hi, we found a bug on the plugin on php8 that prevented forms from being sent. Only on forms with dropdowns and other array-type files.

We would get a 500 error (visible only on the inspector)

We figured it was an error on line 848 of file /wp-content/plugins/contact-form-7-to-database-extension/CF7DBPlugin.php

It is now:
$value = is_array($value) ? implode($value, ', ') : $value ;

And it should be:
$value = is_array($value) ? implode(', ',$value) : $value ;

Would be great if you could fix it for future updates. Thanks
