can we still have a test that deletes sentry-cli and then run the build again to verify it does not fail, but extracts the cli again?

LGTM just left one comment about a test.

And also, would be great if we test that after updating the cli/gradleplugin version it uses the new version instead of an old one. idk if we can easily create a test for that, but verifying it locally would be enough already
