#   resolve-version.sh 19.1.0     that release
#
# Prints two lines, `version=<x>` and `sha512=<base64>`, so a workflow can append the
# output to $GITHUB_OUTPUT as it is. Gitea #156: the test image follows the channel
# rather than a pin, because installed apps update on their own and a pinned old
# version would be tested against while users run the new one.
