Subject: [PATCH] Specify version for bazelisk via `USE_BAZEL_VERSION`

bazelisk does not read the `.bazelversion` file when there is no WORKSPACE and first fetches the latest Bazel version,
which causes a warning and later fetches the Bazel version specified in the `.bazelversion` file.

See https://github.com/bazelbuild/bazelisk/issues/523
