Add language support for recapcha

[canesin]

reCaptcha is always in english with useraccounts. You should add a hl field in the reCaptcha configuration, or set it equal to the T9n setting. Something like this for loading the javascript will suffice:

script src='https://www.google.com/recaptcha/api.js?hl={{languageTag}}'

btw, the widget won't change language reactively...

If you really need it, you could try to remove the recaptcha widget and re-render it manually after having loaded again the api with the new language code when the language changes...
