chore: Upgrade Python requirements (#37710)

* 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.
