title: Model form labels translation
body: <p>I have included form labels in my translation as follows:</p>
  <pre><code>class GuestEmailForm(forms.ModelForm):
      class Meta:
          model = Guest
          fields = ['email']
  
          labels = {
              'email': _('Add your email for updates'),
          }
  </code></pre>
  <p>However, even though they show up in my translation files and I have added translations, they do not show up translated.</p>
  <p>Is there a special way to handle labels in model forms?</p>
