Add Amazon Linux 2023 images
Related to omnibus-gitlab#7739 (closed)
Not switching the images because if we do that and some other changes (like a version) update happens in this repo before we change the builds themselves in omnibus-gitlab
, the packages will suddenly get built with AL2023 as soon as we bump the BUILDER_IMAGE_REVISION
in omnibus-gitlab
. This way, we can control when these new images actually get used.
