i18n: register all 8 translated locales in Starlight config

[leaanthony]

Registers all 8 translated locales in docs/astro.config.mjs so the Starlight language switcher surfaces translated pages.

Changes

docs/astro.config.mjs — adds 8 locale entries to the Starlight locales block:

Locale key	Label	Lang tag
zh-cn	简体中文	zh-CN
zh-tw	繁體中文	zh-TW
ja	日本語	ja
ko	한국어	ko
ru	Русский	ru
fr	Français	fr
pt	Português (Brasil)	pt-BR
de	Deutsch	de

Without these entries, translated .mdx files exist on disk but Starlight doesn't expose them through the language switcher (as noted in #5343).

Walkthrough

The documentation configuration is expanded to support multiple languages in the Starlight site integration. The locales map previously contained only English; it now includes nine language variants (English, Chinese Simplified/Traditional, Japanese, Korean, Russian, French, Brazilian Portuguese, German) with their corresponding labels and language settings.

Poem

🐰 A multilingual leap so fine,
Nine tongues now grace the docs' design,
From East to West, the languages bloom,
In Starlight's bright and welcoming room!
The rabbit hops with joy profound. ✨
