Plugin still has deprecated code for PHP 8.3 and above

Both the below files in the plugin still use deprecated code:

Deprecated: mg_api_last_error(): Implicitly marking parameter $error as nullable is deprecated, the explicit nullable type must be used instead in wp-content/plugins/mailgun/includes/wp-mail-api.php on line 36
Deprecated: mg_dump_headers(): Implicitly marking parameter $headers as nullable is deprecated, the explicit nullable type must be used instead in wp-content/plugins/mailgun/includes/mg-filter.php on line 259
