improv(tests): add e2e test with collector for all of our OTLP exporters

After changing the default port I can assume it will not be working. Could you please update the docker to ensure it is still working fine (use the latest docker image 0.25)?

Sure, but i think it would make sense to make test with the collector (end to end pretty much) itself in our pipeline so this doesn't require manual testing in the future
