Description

Setting language in settings to English does not persist between reloads of page because internally, Uptime Kuma does not recognize that language as valid.

👟 Reproduction steps

1. Ensure auto-detected language is something else than English
2. Go to Settings -> Appearance -> Language and select English
3. Refresh page

👀 Expected behavior

Language settings is persisted according to user preference

😓 Actual Behavior

Language is reverted to auto-detected one based on locale
