i18n(ja): use katakana for the Git operations commit, push, and fetch in the ai/ti docs

[yahonda]

What is changed, added or deleted? (Required)

Uses the common Japanese renderings コミット, プッシュ, and フェッチ for the Git operations commit, push, and fetch in the prose of two ai/ti/ docs. These words had been left in English in Japanese sentences, for example 「必要な変更を commit してください」. Elsewhere in the JA docs, Git operations in prose are written in katakana (for example tidb-cloud/branch-github-integration.md: 「新しいコミットをプッシュする」), and the same file already uses 未コミット and オンデマンドフェッチ.

• ai/ti/guides/ti-git-workspace-for-agents-example.md: L18, L76, and L93.
• ai/ti/reference/ti-filesystem-git.md L8. The whole list "status, edit, add, commit, fetch, and push" is rendered as operations: ステータスの確認、編集、追加、コミット、フェッチ、プッシュ.

Commands and identifiers in code (git commit, ti fs commit-layer, --commit-ish, …) are unchanged.

This follows up the review of the 2026-10-01 sync (#24132).

Tips for choosing the affected version(s):
