Missing translation in twofactor_gauthenticator_form.js for Proceed Button

[umsmin]

My Roundcube Installation v1.6 is like me in German but the Proceed Button is in English.

For the moment I made a quick and dirty hack in the twofactor_gauthenticator_form.js. I changed at nearly the end of the file:

    // create textbox
    $('form > table > tbody:last').append(text);
    $('#rcmloginsubmit').html('Proceed');

to

    // create textbox
    $('form > table > tbody:last').append(text);
    $('#rcmloginsubmit').html('Überprüfen');

I don't know how to add it into the translations. Maybe someone can do it.

Thanks
