Prints the tailscale versions integration tests use, with optional filter and format flags. Source of truth stays in hscontrol/capver; CI shells out to this instead of duplicating the version list in YAML. Examples: hi list-versions hi list-versions --set=must --exclude=head hi list-versions --set=all --format=json
