Merge with eisop/templatefora-checker#1

CI doesn't pass, looks like the project is cloned in the wrong location.

@wmdietl This PR dependens on jdk23 and should be merged after eisop/templatefora-checker#2

The error looks more like some problem with what git repository is cloned. But I've merged eisop/templatefora-checker#2 now.

There still seems to be some git issue, see here.
No similar output is made for the demos task.

I think the pull error is expected as I am cloning branch use-eisop-dependency for templatefora checker and pull the original branch. After we merge both PRs, it would be fine.

Thanks!

Regarding this comment:
In CI we are cloning something from the PR authors org/branch and then here we're trying to pull in the eisop version. I don't think that is correct.

We should do what we do in the createCloneTask in build.gradle: simply pull if the directory already exists.
Can you open a separate PR that reduces the duplication between the demos and template tasks by reusing the createCloneTask (or extracting some of its logic) and then using that here.
