Test failures inside docker container dont cause pipeline to fail

Hi,

First off, great module - thanks for the effort! We are running tests via a bash script running inside a docker container. The container is set up as a service in docker-compose via a test run script which also sets up an empty SQL DB where we run tests:

```bash
UID="$(id -u)" GID="$(id -g)" ENVIRONMENT="azure" docker-compose -f docker-compose.yml config > docker-stack.yml
docker-compose -f docker-stack.yml build --no-cache
docker-compose -f docker-stack.yml down -v --remove-orphans
docker-compose -f docker-stack.yml up -d
docker-compose -f docker-stack.yml exec -T backend python /app/app/scripts/insert_scripts/create_database.py
docker-compose -f docker-stack.yml exec -T backend bash /app/app/scripts/test.sh "$@"
docker-compose -f docker-stack.yml down -v --remove-orphans
exit $?
```

The test.sh script itself is very simple:
```bash
pytest "$@" --cov /app/app --cov-report html
exit $?
```
(I added the `exit $?` on the recommendation of an answer on [ this stack overflow post](https://stackoverflow.com/questions/72189493/running-python-unittests-in-azure-pipeline-doesnt-fail-even-though-it-should))

I noticed that the build doesnt fail if the tests fail. I would normally rectify this by setting the option `failTaskOnFailedTests` for the `PublishTestResults@2` task, but this is abstracted away when using pytest-azurepipelines. How would I go about ensuring that the pipeline exits with a failure if any tests fail? Any help would be greatly appreciated!

just in case im doing something dumb, here is the pipeline.yml file:
```yaml
trigger: none
pr:
branches:
include:
- main

- name: ENVIRONMENT
value: "azure"
- group: sor-data-api-ci-variables

exit $?
