Annotate - update BE dependencies about cellxgene

[atarashansky]

It appears that a FE plugin called obsolete-webpack-plugin is interfering with the GHA testrunner (see failing tests on #2634).

Assuming that the issue is due to out-of-date FE dependencies, then this ticket is blocked by the one to upgrade FE annotate deps (#2617).

@dsadgat Just as an FYI, cellxgene as it currently is does not appear to work on my M2 machine. A fresh install of main's requirements-dev.txt on my machine on a clean virtual environment does not work. This will probably end up taking me a bit longer than someone without an M1/M2 machine, since I'll have to first figure out how to get my local environment set up to run cellxgene as it is (if possible) before I can start updating the backend dependencies.

@atarashansky I believe you have annotate working? Could you take this one over and pin the Werkzeug dependency via https://czi-sci.slack.com/archives/C0247APK621/p1699544094837979
