URL: https://github.com/apache/datafusion/pull/22549
## Which issue does this PR close?
N/A - follow-up maintenance.
## Rationale for this change
The sqllogictest runner runs test files in parallel but each file
sequentially, so it prioritizes known long-running files to run first to
minimize total wall-clock time. This list was last set in #20656.
The relative timings have since shifted. Running with the
`--timing-summary` flag now reports a different ordering of the longest
files, with `nested_loop_join_spill.slt` having become the longest by a
fair margin:
```text
$ cargo test --profile=ci --test sqllogictests -- --timing-summary
Per-file elapsed summary (deterministic):
1. 5.437s nested_loop_join_spill.slt
2. 3.471s push_down_filter_regression.slt
3. 3.458s aggregate.slt
4. 3.065s joins.slt
5. 2.852s aggregate_skip_partial.slt
6. 2.832s imdb.slt
7. 2.453s window.slt
8. 1.831s group_by.slt
9. 1.282s clickbench.slt
10. 1.055s datetime/timestamps.slt
11. 0.994s array/array_has.slt
12. 0.840s cte.slt
13. 0.748s sort_pushdown.slt
14. 0.714s push_down_filter_parquet.slt
15. 0.668s projection_pushdown.slt
```
## What changes are included in this PR?
- Update `TEST_PRIORITY_ENTRIES` in
`datafusion/sqllogictest/src/test_file.rs`
to match the latest `--timing-summary` ordering, promoting
`nested_loop_join_spill.slt` to the front and adding several newly
long-running files.
- Update the example output in the accompanying doc comment.
## Are these changes tested?
Yes - the existing `prioritized_files_are_first` unit test passes.
## Are there any user-facing changes?
No.
Follow-up to #20656.
