Using bzlmod with Bazel 6

1. Enable with common --enable_bzlmod in .bazelrc.
2. Add to your MODULE.bazel file:

bazel_dep(name = "rules_haskell", version = "0.18")

Using WORKSPACE

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
    name = "rules_haskell",
    sha256 = "d1f0e1bd4f1d5e248b2882bfdc7c31a146112f9d85b9d2f0ef77e78d02ecba45",
    strip_prefix = "rules_haskell-0.18",
    url = "https://github.com/tweag/rules_haskell/releases/download/v0.18/rules_haskell-0.18.tar.gz",
)
