I think this can be move to dev dependencies, but should not be remove because
this was added because scanspec plans were not running in blueapi out of the box, so we added a test to specifically test it. (When there were lot of pydantic changes that were breaking scanspec)

If this happens we will not be able to know if the latest scanspec is working with blueapi.

This is still testing if blueapi can run scanspec scans, it's just not testing the serialization part which isn't normally used by the server.
