  "message": "[ci] Update base docker image to use Ubuntu 20.04 (#13907)\n\nUbuntu 18.04 reached end of life on May 31, 2023:\r\nhttps://ubuntu.com/blog/18-04-end-of-standard-support So we announced\r\ndropping support for it in our CI:\r\nhttps://groups.google.com/g/iree-discuss/c/XrKjhUmz2CA/m/C96Z9zxiAgAJ\r\n\r\nThis commit upgrades the base docker image to use Ubuntu 20.04, sha256\r\nfound in https://hub.docker.com/_/ubuntu for focal-20230412.\r\n\r\nAlong the way, we perform some cleanup of the docker scripts:\r\n\r\n* Install Vulkan SDK from LunarG Ubuntu repo, given that 20.04 is\r\nofficially supported there. This requires bumping the version to\r\n1.3.250.\r\n* No need to install GCC 9 separately anymore---Ubuntu 20.04 by default\r\nuses GCC 9.\r\n* No need to check whether we are Ubuntu 18.04 anymore when deciding\r\nIREE dependency packages to install.\r\n\r\nFixes https://github.com/openxla/iree/issues/11782\r\nProgress towards https://github.com/openxla/iree/issues/13830",
