e2e tests

[xdxxxdx]

As the docker compose file is deleted by the pull request:
e95bdbc#diff-5a009985c3c2b86314420cbabdc342063e0b66628bf25b9f879911085079a2c7
I am wondering how the https://github.com/eclipse-edc/FederatedCatalog/tree/main/system-tests/end2end-test#test-execution
is supposed to run.

Thanks so much

we have a way of spinning up runtimes from within the JUnit runner using dedicated URLClassLoaders. The documentation is wrong though, and it should be removed.
