This code does not have any dependencies that are specific to any specific
version of ubuntu. So instead of testing on a specific version and then needing
to do work to keep the versions up-to-date, we switch to the ubuntu-latest
target which should be sufficient for testing purposes.
This work is being done as a part of https://github.com/openedx/platform-roadmap/issues/377
closes https://github.com/openedx/edx-platform/issues/35314
