Document how to add this as dependency

[hofbi]

I would greate to have a short documentation in the readme on how to add this as a dependency to your project.

Should be also related to #370, since bzlmod simplifies the setup.

Agreed, this would be in line with other Bazel rules repos whose root README is typically installation instructions

For anyone coming across this issue in the meantime try

# deps.bzl
load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

def vaticle_bazel_distribution():
    git_repository(
        name = "vaticle_bazel_distribution",
        remote = "https://github.com/vaticle/bazel-distribution",
        commit = "0040e492db47eb83681a62ddf8491a7218633164",
    )

# WORKSPACE
load("//:deps.bzl", "vaticle_bazel_distribution")
vaticle_bazel_distribution()

# load modules you need from bazel_distribution here, e.g:
load("@vaticle_bazel_distribution//common:deps.bzl", "rules_pkg")
rules_pkg()
load("@rules_pkg//:deps.bzl", "rules_pkg_dependencies")
rules_pkg_dependencies()

We haven't yet migrated to Bzlmod but there is an open PR that would initiate the process, Bzlmod instructions will be released as they become available.
