Deployment of extension classes fail when Keycloak testcontainer runs on a remote docker host

First of great work on creating this very useful test container! I do however hit a bump. When the Keycloak testcontainer is spawned on a remote docker host, the extension classes are never deployed. I suspect it has to do with the addFileSystemBind which is registered on the directory. This directory is not present on the host where the Keycloak testcontainer is running.

There are not much other possibilities if we need to copy the resources to the container. All tests are still green. With Keycloak.X I don’t copy all the single files from the directory, but create a .jar archive on the fly first and copy this file to the container (due to requirements in KC.X and the Quarkus architecture). Tests work also for KC.X.
