A repro used to show case that renovate bot does not try to update grpc-java bazel module version,
because the version is considered to be pinned as it is in single_version_override instead of
bazel_dep.
The reason pinning the version in single_version_override is that a patch towards MODULE.bazel
is needed (see bazelbuild/bazel#23757 (comment) for details).
Since this patch is still valid for a later version of grpc-java (1.67.1), it makes sense for
renovate to suggest a version bump.
