Yes

Brief description of what is fixed or changed

If not using module dependencies, there is a risk of including the same dependency twice as Bzlmod cannot resolve this correctly.

Looks like we need to rerun gazelle?

Oops, I forgot to update the lock file. Should be fixed now.

[johanbrandhorst]

Looks like there still a minor lockfile issue

I just ran bazel run //:gazelle as the CI. Let's see if this fixes it.
