Update locales v10.10.0

[flodolo]

This takes localization from master and update the v10.10.0 branch

Discussion happening over email.

@flodolo commented in that email, but the failures caused by commit 6863352 make this branch significantly more risky. I'd recommend resubmitting w/o that commit, and then handling that separately.

I've checked, there are no commits passing tests on the v10.10.0 branch since Jul 20

Last commit has exactly the same type of failure

While the diff on this patch is big, it only touches localized FTL files (and doesn't touch en-US), so I don't see how it can make tests fail.

Tests have been failing because we removed the Full Page functionality, which was used by the tests. So yes, the failure is expected/OK
