[Maintenance] Fix issue with snapshots not updating locally for api endpoints tests

[thetif]

Description and related issues

We are having an issue where if you update the snapshots for the api endpoint tests, they only update in docker, not locally, so you can't check-in the updates. This wasn't an issue before we switched to workspaces, I think. We tried binding the volume to the local file system, but the CI didn't like that. We need a better solution that works locally to update snapshots without having to change the compose file and that still runs in the CI. Start by looking at the pre-workspaces code in the Dockerfiles and docker-compose.endpoint-test.yml.

This task is done when…

• [ ] look into how it was done before we switched to workspaces
• [ ] determine a solution
• [ ] implement solution
