使用Spring Boot Maven插件构建镜像时因GCR权限不足导致GitHub Actions构建失败求助

各位好，我遇到了一个棘手的问题：我的项目之前用GitHub Actions构建一直很顺利，但最近突然失败了，报错是拉取GCR上的Paketo构建器镜像时权限不足。

具体的错误栈信息如下：

Caused by: org.springframework.boot.buildpack.platform.docker.transport.DockerEngineException: Docker API call to 'localhost/v1.24/images/create?fromImage=gcr.io%2Fpaketo-buildpacks%2Fbuilder%3Abase-platform-api-0.3' failed with status code 500 "Internal Server Error" and message "Head "https://gcr.io/v2/paketo-buildpacks/builder/manifests/base-platform-api-0.3": denied: Caller does not have permission or the resource may not exist 'read'.

我的GitHub Actions workflow里相关的构建步骤是这样的：

- name: Build Layered Jar with Maven
  run: mvn clean install spring-boot:build-image -e -B -U --file pom.xml -P test -s src/main/resources/settings.xml

我有点困惑，之前构建完全没问题，为什么突然就出现权限拒绝了？有没有可能是GCR上这个镜像的权限设置变了？或者GitHub Actions的默认runner访问GCR的策略有更新？有没有大佬遇到过类似问题，能给点排查方向或者解决办法吗？
