Redirect to learning microfrontend, except for exams

Create flag for Courseware MFE staff rollout.

Create the COURSEWARE_MICROFRONTEND_COURSE_TEAM_PREVIEW
CourseWaffleFlag (courseware.microfrontend_course_team_preview) to
enable us to roll out the new Courseware MFE as a preview to
select course teams without affecting their students. TNL-7117

This commit also fixes an issue where these links are shown in Old
Mongo courses (TNL-7116). Old Mongo is marked for deprecation
(DEPR-58), and is not intended to ever be supported by the new MFE.

Show MFE preview to course staff (if waffle set)

This is a fix to PR #23222.

Check to make sure that "activate_block_id" is actually a Unit
(VerticalBlock) before using it to build a link to the Courseware
MFE. We were previously sending sequence block keys here, causing
the MFE to render a whole sequence where only a unit was desired.

Fixes TNL-7115

Show a link the courseware MFE to course staff if the
ENABLE_COURSEWARE_MICROFRONTEND feature is enabled and the
REDIRECT_TO_COURSEWARE_MICROFRONTEND CourseWaffleFlag is active
for that course. Previously only global staff could see this link.

This commit also adds ENABLE_COURSEWARE_MICROFRONTEND to
lms/envs/common.py and makes this value True by default on
devstack, since that front end application should soon be part
of devstack: https://github.com/edx/devstack/pull/484

AA-55: Updating edx-when version

Python Requirements Update

Use relative dates flag for dates widget v2

The video thumbnail and transcript tasks were the only things using chord_task from
edx-celeryutils, which in turn was blocking django-celery removal. But, they're no longer used.

Co-authored-by: Diana Huang <diana.k.huang@gmail.com>

Switch from a separate waffle flag for the dates widget v2 work
and just use the relative dates experiment flag instead.

* pass teamset type existence flags to the teams tab view
