* chore: Upgrade Python requirements * build: Downgrade edx-submissions for now. The latest version changes a method signature and so code here will need to be updated before that can land. There is already a PR to pick up that change https://github.com/openedx/edx-platform/pull/37528 so it doesn't seem worth it to add the constraint so just downgrade the package in this PR so we can land the rest of the updates. --------- Co-authored-by: Feanil Patel <feanil@axim.org>
