Hi @gen1us2k. This is unfortunately one of those it's not that simple cases. We're very keen to keep the versions pinned between our Bazel dependencies and our dep dependencies the same, and this PR only updates the dep version. Indeed, the comment just above the line that you edited points to the other file that you'd need to edit. Can you see if the Bazel version can be updated in this fashion too?

The longer term solution to this is #755. If you are interested in implementing that, please do, but this PR as it is is incomplete.
