Description
Description
the bazel build currently uses rules_rust 0.59.2
I have had need to use features that are only available in rules_rust 0.70.0, although fortunately only for testing things on my local machine
I have made efforts to upgrade to 0.70.0: https://github.com/lowRISC/opentitan/pull/30030
unfortunately the latest rules_rust makes use of rules_python, which tries to fetch python package metatdata at build time, which breaks the airgapped build
We need to patch rules_rust to not do this, if we want to upgrade it. currently we can safely stay on the older version.

Research direction
Start by reading pull request 30030 and the current Bazel dependency setup for rules_rust 0.59.2. Trace how rules_rust 0.70.0 brings in rules_python and fetches package metadata, then verify that the upgraded build still works in the airgapped configuration without that network access.
