ubuntu-slim is a new cost-efficient runner to fit lightweight jobs. We can use this to save ASF infra usage (if possible). By *lightweight* I mean jobs that run for less than a minute and are not easily affected by other concurrently running jobs on the same host. This topic was raised in the Apache ORC project and later adopted by iceberg-cpp. We believe it could also benefit other projects under the Apache Iceberg umbrella.

`check-md-link` requires a Docker environment, while `ubuntu-slim` already runs inside Docker, so reverting this change.
