GitHub has no generic package registry, so releases become GitHub release assets. The updater and install.sh read releases/latest/download and releases/download/<v>/, plain redirects with no API rate limit. make release publishes a draft with all assets, then makes it latest. make release-gitea publishes the same version to the old Gitea registry for binaries that still update from there, and refuses until GitHub serves it.
