Improve consistency by prefering bazel_dep over Go

Letting the bazel_dep and Go dependency participate equally in the
version resolution is creating various inconsistencies. This can lead to
to a root module having to either use `inject_repo` or `use_repo` and
`override_repo`.

Resolve this by consistently preferring the `bazel_dep` over the Go
dependency. Keep the existing code that warns (or can fail) if the
dependencies are at different versions.

Example MODULE.bazel:
```
module(
    name = "bazel_dep_should_win",
)

bazel_dep(name = "rules_go", version = "0.53.0")
bazel_dep(name = "gazelle", version = "0.42.0")
bazel_dep(name = "circl", version = "1.3.8")

go_deps = use_extension("@gazelle//:extensions.bzl", "go_deps")
go_deps.from_file(go_mod = "//:go.mod")
```

And the go.mod referring to a newer version.

Fixes #2060
