Subject: [PATCH] feat: add Uzbek language support

Adds the Uzbek (`uz`) locale to the i18n supported locales list, along
with the corresponding FormatJS plural-rules and relative-time-format
locale data, the i18n-iso-countries locale registration, and the
messages PropTypes shape. Mirrors the prior Vietnamese support change
(#825).

Uzbek translations already exist for downstream MFEs in the
openedx-translations pipeline; this change lets frontend-platform
recognize `uz` as an expected locale (silencing the dev-mode
"Unexpected locale" warning) and ensures plural/relative-time
formatting and localized country names work for `uz`.
