The fourth argument is args, meant to be a dict.
With an increasing number of docker images, the overhead of hashing the compressed contents of the docker context tars becomes visible when loading the toolchain kind during Firefox builds. But the really interesting part for the hash is the uncompressed contents. Whether they are compressed with gzip at level 9, gzip level 1, bz2 or zstd, it doesn't matter for the resulting docker image. So it makes sense to only hash the uncompressed contents, which is much faster.
