[bazel] update .bazelversion to 8.0.0 (#119425)

Fixes:

ERROR: The project you're trying to build requires Bazel 7.3.0
(specified
    in llvm-project/utils/bazel/.bazelversion), but it wasn't found in
    /usr/bin.

    You can install the required Bazel version via apt:
      sudo apt update && sudo apt install bazel-7.3.0

If this doesn't work, check Bazel's installation instructions for help:
      https://bazel.build/install/ubuntu
