Update l10n for 1.37.x (Chromium 100) - Part II.

[mkarolin]

Download the latest l10n from Transifex.

Test plan:

https://github.com/orgs/brave/teams/legacy_qa should run through a few locals just to make sure that nothing obvious has regressed. Shouldn't spend too much time on this though.

Above requires 1.37.114 or higher for 1.37.x verification.
