Generating LICENSES.txt and source code package
From top-level kpt directory:
./scripts/create-licenses.sh
This script will generate files LICENSES.txt and lib.zip in the
top-level directory. These files will eventually be included in the kpt
release tarball. This script will first run go mod vendor to
generate the vendored dependencies. The script removes the contents
of the vendor directory upon success.
