[Maria-docs] Usage of an informal tone on the documentation on the KB

There are no details about what tone should be used on the KB pages (https://mariadb.com/kb/en/meta/contributing-to-the-mariadb-knowledge-base/) and many of the KB pages use an informal/personal tone with the use of the first (i, we) and second person (you) which i think doesn't suit very well for a enterprise-grade product documentation, at least it doesn't feels right when translating pages to French. Is that intentional or not and should there be a rule about that at least on documentation pages?
