i18n-ja-release-8.5: Vale PingCAP.ZhPunctuation reports every Japanese full stop as an error #24533

Problem

On the i18n-ja-release-8.5 branch, the Vale rule PingCAP.ZhPunctuation reports every Japanese full stop 「。」 as an error:

[PingCAP.ZhPunctuation] Don't use Chinese punctuation (。) in English text.

The Japanese docs use 「。」, 「、」, and 「」 as correct Japanese punctuation, so every Japanese pull request gets a large number of false errors:

• On i18n(ja): fix TiDB Cloud Starter PostgreSQL docs found in a full review #24532, the Vale job reported 104,786 results. GitHub shows at most 10 annotations per step, so any real finding is lost in the noise.
• CodeRabbit picks up the reviewdog output and posts the false errors as review comments. For example, i18n(ja): add missing TOC entries and fix entries in the develop and best practices TOCs #24512 had them on glossary.md and cached-tables.md, and i18n(ja): fix TiDB Cloud Starter PostgreSQL docs found in a full review #24532 had one on tidb-cloud/starter/import-with-psql.md. Each one has to be answered and withdrawn by hand.

The vale check itself passes, so these errors do not block merging. They only add noise to Japanese reviews.

Cause

• .vale.ini applies the PingCAP style to every Markdown file ([*.md] → BasedOnStyles = PingCAP). The i18n-ja-release-8.5 branch uses the same file.
• styles/PingCAP/ZhPunctuation.yml matches ！|？|，|。|：|；|“|”|’|‘ with no language or path condition. Its message says "in English text", but on the Japanese branch every file is Japanese text.

Suggested fix

On the i18n-ja-* branches only, turn off the rules that are meant for English text. For example, in .vale.ini on i18n-ja-release-8.5:

[*.md]
BasedOnStyles = PingCAP
Vale.Avoid = YES
PingCAP.ZhPunctuation = NO

Other PingCAP rules are written for English as well, such as Spacing, HeadingPunctuation, and OptionalPlurals, and might need the same treatment. The English branches (master, release-*) should keep ZhPunctuation, because there it catches real Chinese punctuation in English text.
