Test batch_run more extensive in CI

We are lacking test coverage of [`batch_run`](https://github.com/projectmesa/mesa/blob/main/mesa/batchrunner.py) in CI. Especially more example models using batch_run in CI could be useful.

See https://github.com/projectmesa/mesa-examples/issues/126 and https://github.com/projectmesa/mesa/pull/2183.

Start by reading mesa/batchrunner.py and the related mesa-examples issue #126, then review pull request #2183 for existing context. Add CI coverage using more example models with batch_run; done means those cases run successfully in CI.
