Describe the bug

Substrait round trip fails for a query that produces a logical plan where the Sort node includes a fetch.

As an example,

Sort: data.b ASC NULLS LAST, fetch=2
  Filter: data.a > Int64(1)
    TableScan: data projection=[a, b, c, d, e, f], partial_filters=[data.a > Int64(1)]

Upon returning from the round trip produces

Sort: data.b ASC NULLS LAST
  Filter: data.a > Int64(1)
    TableScan: data projection=[a, b, c, d, e, f], partial_filters=[data.a > Int64(1)]

the fetch is lost.

I'm happy to take and fix this issue, but I wasn't sure where the fix should be made. Should this fix the Sort Rel in substrait that cannot hold a fetch member? Or should this be a fix in the substrait producer to produce a plan with a Limit and a Sort?

To Reproduce

Add a test to datafusion/substrait/tests/cases/round_trip_logical_plan.rs such as

#[tokio::test]
async fn select_with_filter_sort_limit() -> Result<()> {
    roundtrip("SELECT * FROM data WHERE a > 1 ORDER BY b ASC LIMIT 2").await
}

in this repo, run

cd datafusion/substrait
 cargo test -- --nocapture select_with_filter_sort_limit

Expected behavior

A round trip for this plan should work.
