This message is intended to fight misinformation around the Russian aggression of
Ukraine, precisely for Russian residents that are kept unaware of the atrocities
that Vladimir Putin started in February 2022.

Please do help spread this message: good people will try helping, but they first
need to know.

Raise awareness of current Russia-Ukraine situation, targeting Russian 🇷🇺  readers

I'm not sure itl brought any value to the project. The api is solid and
the API doesn't changes that much. That is why I'm removing it, we could
also just use the package though the CI without requiring it in the
composer.json file.
