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.

## Which issue does this PR close? - Closes #20870. ## Rationale for this change `ubuntu-slim` is a cost-efficient runner that can save ASF infrastructure resources for lightweight CI jobs. This was raised in the Apache ORC project and adopted by other Apache projects like iceberg-rust (apache/iceberg-rust#2187). ## What changes are included in this PR? Switch 6 lightweight CI jobs from `ubuntu-latest` to `ubuntu-slim`: - `take.yml`: `issue_assign` — curl API calls only - `large_files.yml`: `check-files` — git commands only - `stale.yml`: `close-stale-prs` — actions/stale - `labeler.yml`: `process` — actions/labeler - `codeql.yml`: `analyze` — codeql-action on Actions YAML - `dev.yml`: `prettier` — setup-node + prettier ## Are these changes tested? CI only — this changes the runner type, not workflow logic. ## Are there any user-facing changes? No.
