test.yml: use image cache with parameters created from template
Use `actions/cache@v4` with following params: path: ".download/by-url-sha256/$(echo $location | sha256sum | cut -d' ' -f1)" key: "digest-$digest" enableCrossOsArchive: true To make the image cache cross-platform, the cache directory is specified using a relative path from the working directory, and the platform-specific cache directories are accessed via symbolic links. This should reduce the cache size used by the CI. Signed-off-by: Norio Nomura <norio.nomura@gmail.com>
