refactor(i18n): automatic locale data (#1725)

* chore(i18n): dep bump + automatic locale data

Small i18n refactor that  makes things more future-proof:
ipfs-shipyard/i18n#9

* fix(i18n): regression in Trans

Latest i18next-icu uses upstream intl-messageformat for plurals,
unfortunately it means we no longer can mix tags with plurals in Trans
element. This is a cosmetic fix that makes the entire label a link.
