More translateable text for website & doc side panel

[Blueberryy]

I wish someone can make https://readthedocs.org/ website fully translateable and these from doc side panel
"On Read the Docs", "Project Home" and "On github"
"Hosted by Read the Docs"
"Search docs"
"Languages"

Hi, those are using translations

readthedocs.org/readthedocs/api/v2/templates/restapi/footer.html

Line 42 in c86f18a

<dt>{% trans "Versions" %}</dt>

we just need to update/add the translations for the language you are using on your browser. #4462
