chore: update edx-enterprise to 3.27.9

We control rollout of the Learning Sequences REST API with the
USE_FOR_OUTLINES (learning_sequences.use_for_outlines) course waffle
flag. But sometimes we're going to want to be able to take a look at
production data output of this API before explicitly turning the API on
(and switching over to it) for the Courseware MFE. To do this, we're
going to make the availability base itself purely on the waffle flag and
course type (Old Mongo courses are not supported), and allow people to
"peek" at what the API would have given if it was rolled out by passing
an explicit "force_on=1" querystring param.

This is work to support the rollout of TNL-8330.

* [fix] Fix certificate available date sync

We were syncing the course available date to every course in
credentials. Since credentials doesn't understand "self-paced" courses,
or course end behaviors, some certificates were time gated incorrectly.
This check make sure to check if the course is not self-paced, and has a
CDB of 'end' before syncing the CA date.

It's often very useful to note the reason we override a waffle.
Who asked for it and why - is it temporary until a feature is
completed or a complete opt-out of the feature itself, etc.

Now there's a text field to leave such comments for your future
self, much like waffle flags themselves.

We are planning on limiting session cookies for LMS, which
will mean that under the old cookie domain, MFEs and other
IDAs would not have access to the language preference of a user.

This moves language preference cookies to use a different setting,
which means that this cookie can be shared.
