[Test PR] Revert "Looks like fuzzing is failing permanently again"

[EliahKagan]

This fork-internal pull request, which is for testing only and should not be merged here (a separate upstream PR would be opened if called for), reverts commit 3d90ab0 to investigate why fuzzing seems to be working when I trigger it via workflow_dispatch yet repeatedly failed when triggered with the pull_request trigger in GitoxideLabs#1536, per GitoxideLabs#1536 (comment).

This PR seems to reproduce the issue I encountered. I think it's related to using the latest version of serde - maybe downgrading it via Cargo.lock would do the trick.

It looks like this has to be tested in a PR on the upstream repository, because using that repository is hard-coded in the image. From this run:
