This text should be translated. See https://docs.djangoproject.com/en/dev/topics/i18n/translation/#trans-template-tag for info but an example of doing simple translations in the template can be found https://github.com/dimagi/commcare-hq/blob/eadc20c1f797fe097e111296804a14327fd4507d/corehq/apps/commtrack/templates/commtrack/debug/bootstrap.html.

Basically you just wrap text: `{% trans "blah blah" %}` and include the module at the top: `{% load i18n %}`.
