Actually you can do this yourself if you don't want to wait. Edit template humanverify_new_recapctha, and near the end is a <script> line. Add the part in red:

<script src="https://www.google.com/recaptcha/api.js?hl={vb:stylevar languagecode}" async defer></script>

or if you want to hard code a language, you can put the code in place of {vb:stylevar languagecode}. The language codes are here: https://developers.google.com/recaptcha/docs/language
