[Bazel CI]Error loading external package: Both '--enable_bzlmod' and '--enable_workspace' are disabled, but one must be enabled to fetch external dependencies

CI: https://buildkite.com/bazel/bazel-at-head-plus-downstream/builds/4093#0191abcf-6360-4d78-8ab8-5aea2636dbb1

Platform: Ubuntu

Logs:

ERROR: �[0mSkipping '//...': error loading package under directory '': error loading package 'web/versioned': Unable to find package for @@[unknown repo 'bazel_skylib' requested from @@]//:bzl_library.bzl: The repository '@@[unknown repo 'bazel_skylib' requested from @@]' could not be resolved: No repository visible as '@bazel_skylib' from main repository. Was the repository introduced in WORKSPACE? The WORKSPACE file is disabled by default in Bazel 8 (late 2024) and will be removed in Bazel 9 (late 2025), please migrate to Bzlmod.

Culprit: bazelbuild/bazel@5881c38

Note : This issue is due to bazelbuild/bazel#23023. After --enable_workspace is flipped to false, users have to explicitly specify it where it's needed, or fully migrate to Bzlmod.
