Wrong po file for spanish translation

[bielfrontera]

Describe the bug The new file djangocms_frontend/locale/es/LC_MESSAGES/django.po does not contain the spanish translation but the german.

Not sure if there is a team for the spanish translation at transifex or I could submit a PR with the translation.

Spanish translations would be sensational!

@bielfrontera I just checked transifex: Spanish translations are empty. If you let me know your email, I can invite you to the team. Please let me know privately on slack: https://django-cmsworkspace.slack.com/archives/CQ97U91UM
