Rebuild for checkmake 0.3.2.

Hi! Do you have a moment to rebuild and repush this? There's [at least one blocking bug](https://github.com/checkmake/checkmake/issues/253) in the current version of your container that's been fixed on `main`.

I would very much like to lint everything in my project, including the Makefiles, but they are blocked on this misleading non-error. It's probably not the only thing that's been fixed in the last four years!

I see it was _supposed_ to take care of itself, but your [nightly build](https://github.com/cytopia/docker-checkmake/actions/workflows/action_schedule.yml) has turned itself off for lack of interest:

> This scheduled workflow is disabled because there hasn't been activity in this repository for at least 60 days. Enable this workflow to resume scheduled runs.

Thanks 😉
