fix: Upgrade deps, forcing a packaging downgrade, fixing safety

The safety run was failing, because new versions the packaging
are extremely pip'd and fail in interesting ways
Newer versions of our other dependencies are aware of this,
and their hardcode a dependency on an _older_ version of packaging

So we upgrade deps to force a dep downgrade :)
