Related issue(s)

Description

This adds jobs to the release workflow that trigger creation of binaries for that tag (using the build-nargo repository) that will be uploaded to the release tag.

These only trigger if release-please has created a tag, so nothing extra is added for normal merging workflows.

Summary of changes

Added a step for each target platform.
