Accept multiple package names in bin/release --package

The rc trigger passes '--package omarchy omarchy-settings', and bin/build
already consumes every name up to the next --option, but bin/release only
took one — the second name fell through to 'Unknown option' and the
release exited before building anything. Parse greedily, like bin/build.
