docs: add 16MB size limit note for plugin publishing (#8108)

Add documentation to clarify the 16MB zip size limit for plugin
marketplace submissions, along with practical recommendations:
- Compress static assets like images
- Clean up unnecessary files (.git, __pycache__, etc.)
- Optimize dependency sizes
- Use .gitattributes or release branches

Also mention the option to contact maintainers for manual bypass
when the limit cannot be met.

+> ⚠️ **Size Limit**: The plugin zip package submitted to the marketplace **must not exceed 16MB**. If it exceeds this limit, the CI/CD pipeline will automatically reject the submission.
+>
+> To ensure your plugin passes review and publication smoothly, we recommend the following:
+>
+> - **Compress static assets**: Compress images, audio, and other resource files in your plugin to reduce their size.
+> - **Clean up unnecessary files**: Avoid including directories like `.git`, `__pycache__`, `node_modules`, or development configuration files in your plugin repository. Add a `.gitignore` file to your repository root to exclude them.
+> - **Optimize dependency size**: If your plugin depends on large libraries, consider trimming them down or importing only what is needed.
+> - **Use `.gitattributes` or a release branch**: Reduce the zip package size by including only the files necessary for distribution.
+>
+> If your plugin truly cannot be compressed to under 16MB due to business requirements, please contact the maintainer to manually bypass this limit.

+> 为确保你的插件能顺利通过审核和发布，建议采取以下措施：
+>
+> - **压缩图片等静态资源**：对插件中的图片、音频等资源文件进行压缩，减小体积。
+> - **清理不必要的文件**：避免将 `.git` 目录、`__pycache__`、`node_modules`、开发用配置文件等非必需文件提交到插件仓库中。建议在仓库根目录添加 `.gitignore` 来排除它们。
+> - **优化依赖体积**：如果插件包含体积较大的依赖库，可考虑精简或按需引入。
+> - **使用 `.gitattributes` 或发布分支**：通过只包含发布所需文件的策略来减小 zip 包体积。
