refactor!: remove unused update-assets-dev.sh (#31810)

The file was introduced as part of the "decentralized devstack" spike.
We wanted a working Dockerfile in the edx-platform root,
and we wanted to speed it up by not relying on Paver.

edx-platform now has a working Dockerfile, and it does not use this script.

The paver-free-assets initiative is being continued here:
https://github.com/openedx/edx-platform/issues/31798
It will result in a new, prod-ready asset building script.

-# Usage:
-#   In a CMS or LMS container,
-#   from the directory /edx/app/edxapp/edx-platform, run:
-#     ./scripts/update-assets-dev.sh
-#
-# This file is an experimental re-implementation of the asset complation process
-# defined by the pavelib.assets:update_assets task in
-# https://github.com/openedx/edx-platform/blob/master/pavelib/assets.py.
-# As the script name implies, it is only suited to compile assets for usage
-# in a development environment, NOT for production. 
-#
-# It was written as part of the effort to move our dev tools off of Ansible and
-# Paver, described here: https://github.com/openedx/devstack/pull/866
-# TODO: If the effort described above is abandoned, then this script should
-# probably be deleted.
