Deployed zh translation is stale: enum/use chapter shows English sentence

[IAMLEIzZ]

Problem

On the deployed Chinese translation, one sentence in the "enum → use" chapter renders in English:

https://doc.rust-lang.org/rust-by-example/zh/custom_types/enum/enum_use.html

The use declaration can be used to avoid typing the full module path to access a name:

Everything else on the page is correctly translated to Chinese.

Investigation

• The English source sentence was rewritten in a29d45a (2025-11-17, "enum_use.md: avoid an uncommon term"), which invalidated the previous zh translation for that sentence.
• The updated Chinese translation was merged in PR Update Chinese translations in zh.po #2025 (commit 4d0f115, 2026-07-06, "docs(zh): update translations for 2026-07 upstream sync"). The entry in po/zh.po matches the current source exactly.
• I verified locally with the same toolchain as CI (mdbook 0.5.1 + mdbook-i18n-helpers 0.4.0):

MDBOOK_BOOK__LANGUAGE=zh mdbook build

The built custom_types/enum/enum_use.html renders the sentence correctly in Chinese ("use 声明可以用来避免为访问某个名称而手动输入完整的模块路径：").

So the translation is complete on master; the deployed site just appears to be built from a commit before 2026-07-06.
