几年没接触gitlab了，新版本装完以后代码提交到默认的main分支，master不再是主分支
项目有几十个仓库，研发提交代码后仓库地址和之前的发生了变化
先修改Group的默认分支，不会影响已存在的项目
修改gitlab全局的默认分支
这就引出了需求，要获取当前仓库下所有仓库地址，还要修改所有仓库的默认分支，从main修改为master
生成AccessToken
创建个人访问令牌
填写信息时，确保勾选以下权限（Scopes）：
api
read_api
read_repository
write_repository
admin_mode（如果是要批量修改默认分支，可能需要这个权限）
# 权限解析
api 和 read_api: 基本的 API 访问权限
read_repository: 读取仓库信息
write_repository: 修改仓库设置（包括默认分支）
admin_mode: 管理员级别的操作权限
