@dbkr also I can't add labels to this PR, can you add one which seems suitable?

[dbkr]

Oh, and you'll need to run yarn run i18n rather than manually adding the entries to the file since the CI checks that it gets the same result.

Just need to run prettier now (this is why the ESLint check is failing) and I think this will be good to go.

Ran the lint command as well, @dbkr
