Review bzlmod dependencies and make use of `dev_dependency = True`

[hofbi]

I came over this through rules_multitools which provides https://github.com/bazel-contrib/rules_multitool/blob/b9fa2d73361fa656666e347f7152571add548a1c/multitool/private/hub_repo_template/tools.bzl.template#L3

After adding bazel-diff to my bazel_deps, my list of multitools was suddenly growing with a bunch of formatters coming from aspect_rules_list. This means bazel-diff is exposing all formatter of rules_lint to their dependencies in

bazel-diff/MODULE.bazel

Line 8 in 4ba6b15

bazel_dep(name = "aspect_rules_lint", version = "1.0.2")

. To me, rules_lint should be a dev_dependency as now of your users might need them to run bazel-diff.

In general, we should use this issue to review which dependencies users actually need and which deps should become dev_dependencies.

This sounds good, I have not done a good job marking those deps so far. Feel free to make PR or I can try to remember for later today. Thanks
