Update translations levels (Nov 2021)

With the implementation of the feature to show the translation coverage in the language selection dropdown, the translation levels need to be updated on a monthly cadence.

Proposal

Once the monthly merge of the new translations is complete, update the translation levels data from Crowdin.
