Added a new repository configuration entry to `repos.yaml` for
`cn.org.linyaps.builder.utils`. This repository contains utility
functions for the `ll-builder` project. The addition allows the ll-
builder system to manage and utilize the utility functions effectively.
The `developer` field is added to specify the primary developer in
charge.

Influence:
1. Verify that the new repository configuration is correctly loaded and
processed by the ll-builder system.
2. Ensure that the utility functions within the
`cn.org.linyaps.builder.utils` repository are accessible and usable by
the relevant components of ll-builder.
3. Test the ll-builder system after the new repository is included to
ensure no regressions or conflicts are introduced.

feat: 添加仓库配置

向 `repos.yaml` 添加了 `cn.org.linyaps.builder.utils` 的新仓库配置条目。
该仓库包含 `ll-builder` 项目的实用程序函数。此添加使 ll-builder 系统能够
有效地管理和利用这些实用程序功能。 添加了 `developer` 字段以指定负责的主
要开发人员。

Influence:
1. 验证 ll-builder 系统是否正确加载和处理新的仓库配置。
2. 确保 `cn.org.linyaps.builder.utils` 仓库中的实用程序函数可供 ll-
builder 的相关组件访问和使用。
3. 在包含新仓库后测试 ll-builder 系统，以确保没有引入回归或冲突。
