In my [experiments to remove Batect](https://github.com/oss-review-toolkit/ort/pull/7853) I came across [several test failures](https://scans.gradle.com/s/gpuvz3ix66jiu/tests/overview?outcome=FAILED) when using the published `latest` version of the `ort` Docker image instead of using Batect with `Dockerfile-legacy`:  Problems seem to be: * `ANDROID_HOME` / `ANDROID_SDK_ROOT` is not set (only the former should suffice). * An unknown issue with JRuby / Asciidoctor. * The Git `repo` tool is not in `PATH`.
