fix JSR publishing: single license, runnable by hand

JSR only accepts a single license identifier, not an SPDX expression, so the
dual license shows up as MIT there (the LICENSE file in the package still
lists both). The JSR job moves into its own workflow that release.yml calls
and that can also be started from the Actions tab
