curl config files needs GH token

The following commands at step 9 don't work. That generates files whose content is "404: Not Found". I needed to add "?token=" to get expected get contents.
curl -o api-gateway.yml https://raw.githubusercontent.com/Azure-Samples/java-microservices-aca-lab/main/config/api-gateway.yml
curl -o application.yml https://raw.githubusercontent.com/Azure-Samples/java-microservices-aca-lab/main/config/application.yml
curl -o customers-service.yml https://raw.githubusercontent.com/Azure-Samples/java-microservices-aca-lab/main/config/customers-service.yml
curl -o discovery-server.yml https://raw.githubusercontent.com/Azure-Samples/java-microservices-aca-lab/main/config/discovery-server.yml
curl -o tracing-server.yml https://raw.githubusercontent.com/Azure-Samples/java-microservices-aca-lab/main/config/tracing-server.yml
curl -o vets-service.yml https://raw.githubusercontent.com/Azure-Samples/java-microservices-aca-lab/main/config/vets-service.yml
curl -o visits-service.yml https://raw.githubusercontent.com/Azure-Samples/java-microservices-aca-lab/main/config/visits-service.yml

打开链接的实验页面并检查第 9 步，其中七条 curl 命令会下载配置文件。验证这些 URL 及其响应，然后确认完成的说明会为每个指定的 YAML 文件获取配置内容，而不是获取 "404: Not Found"。
