尝试使用GitHub Actions在线编译瑞萨RZ/G2UL Instructions images

省流：不行

测试流程：

（1）新建项目https://github.com/LV36/RZ-G2UL/

（2）新建文件.github/workflows/RZ-G2UL-images.yml，文本框中输入如下代码：

（3）新建文件local.conf，参照https://github.com/renesas-rz/meta-renesas/releases/tag/BSP-3.0.0-update2中/meta-renesas/docs/template/conf/smarc-rzg2ul/local.conf和参考文档[1]Page 7 of 33自定义功能开启情况

（4）Actions页面Run workflow进行在线编译

3小时左右后编译失败

（5）查看相关文档后发现编译至少需要100G硬盘空间，而Github Action可用空间为30G左右，可用空间不足，白嫖失败。
