Consider relaxing renovate changes for BCR modules

[cerisier]

Any module listed as bazel_dep in rules_zig MODULE.bazel file makes it in the module graph resolution of downstream modules, which means that bumping a dependency here forces it to all downstream dependents.

I would like to argue to stop bumping rules_* modules here and even consider using the bare minimum possible so that version selection of such modules is deferred downstream.

To suppor this argument, here is the result of several discussions in the Bazel slack that led to some default Aspect presets for ruleset authors:

Yes, I agree that this would be better for precisely the reason you describe. But, last time I looked into the renovate configuration (I'm using renovate instead of dependabot) there was no good way to achieve this that wouldn't also stop receiving updates of dev-dependencies. And I would like to keep dev-dependencies up-to-date.
