please update the lockfiles.

The diff doesn't look quite right. The .bazelversion file on release-8.1.0 still says 7.4.1 (https://github.com/bazelbuild/bazel/blob/release-8.1.0/.bazelversion), so we should either generate the lockfiles using Bazel 7.4.1, or cherry-pick 3f9f26f to release-8.1.0 first.
