Subject: [PATCH] Updated Chrome settings

- Adds `--headless`
- Removes shared-memory related settings and disables shm

After doing this, I'm able to run the feature tests. Before adding the headless option I still had trouble with frequent Selenium Chrome crashes, but not since. In any case, those are "resolved" by running `docker compose restart selenium` and re-running the tests.
