Subject: [PATCH] [DOM-59987] Update linux_user_data.tpl for singe-node based
 on AL2023 (#288)

One of the changes from Amazon Linux 2 to Amazon Linux 2023 is switching to nodeadm for the initialization process. The single-node option sets some labels, so we're updating the linux_user_data.tpl to be in YAML format.
