Drop the typescript-api pack from the plugin pipeline

publish.sh --pack produced a local typescript-api tarball so a plugin
could build against the branch API through external_package.json.
In-tree plugins now get the branch API directly via npm_replace_package
in Gerrit, so packing is unnecessary and its broken ordering is removed.
