Move releases to GitHub, with one bridge release on Gitea

Browse Source 
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. See D33.
