The edx-sandbox (secure/codejailed execution context
for edx-platform) still runs in Python 3.5, so certain
modules in common/lib cannot be py-upgraded to use
Python 3.8 syntax.
Specifically, this commit added an f-string to
common/lib/sandbox-packages/verifiers/draganddrop.py,
which broke scoring of deprecated drag-and-drop problems
in codejail.

This reverts commit 8c06b68bbe
Reverts #26731
The code in common/lib/capa/capa/safe_exec needs
to remain Python 3.5-compatible, since edx-sandbox
(ie codejail) is still running Python 3.5.
django-not-configured is an error raised by pylint (with
the pylint-django plugin) when it's not correctly configured.
We should not be applying lint amnesty for such a violation.
