Update description of avoid-ai-writing-cn

• I added one file at data/plugins/<owner>__<repo>.yml — the READMEs are generated, don't edit them by hand / 我新增了一个 data/plugins/<owner>__<repo>.yml 文件（各语言 README 由脚本生成，不要手工编辑）
• I ran node scripts/generate-readme.mjs and committed the regenerated READMEs / 我已执行 node scripts/generate-readme.mjs 并提交了重新生成的 README
• My repo's package.json declares dsh.bundle (not just dsh.client) — example / 仓库 package.json 已声明 dsh.bundle（只有 dsh.client 无法安装）
• My repo is at least 1 day old with 10+ commits / 仓库创建满 1 天且提交数 ≥ 10
• category is one of ui theme model session memory tools skill workflow notify dev market fun, and themes/skins go under theme / category 取值正确，主题/皮肤类请用 theme
• Description states what the plugin does, no superlatives / 描述只说功能，不带营销词
• My repo has the dsh-plugin topic / 仓库已打 dsh-plugin topic

Recommended (not required) / 推荐但不强制：

• 📦 Publish to npm — npm installs are prebuilt and skip the allowBuilds approval, so users get a one-command install / 发布 npm 包：预构建产物免 allowBuilds 授权，用户一条命令装好
• 🔗 Declare official @deepseek-ai/* packages as peerDependencies (not dependencies) — avoids duplicate runtimes inside the profile / 官方 @deepseek-ai/* 包用 peerDependencies 声明（而非 dependencies），避免 profile 里出现重复运行时
• 🖼️ Screenshots go in your own repository now: a screenshots.json beside your package.json, listing image paths. Nothing to add here, and you can change them later without another pull request (how) / 截图现在放在你自己的仓库里：在 package.json 旁边放一个 screenshots.json，列出图片路径。这个 PR 里不用加任何东西，以后想换也不必再提 PR（说明）
