URL: https://github.com/apache/datafusion/issues/10624
### Describe the bug
When unparsing LogicalPlans back to SQL statements for the MySQL dialect,
any plan that includes a `Sort` node will produce a SQL statement that looks
like:
```
SELECT "ta"."j1_id" FROM "j1" AS "ta" ORDER BY "ta"."j1_id" ASC NULLS LAST
LIMIT 10
^--------^
```
The `NULLS LAST` causes issues when run against a MySQL server, as it
doesn't recognize that syntax.
### To Reproduce
Create an Unparser with a MySQL dialect, unparse any plan that includes a
Sort node and observe that the SQL string generated includes the NULLS
FIRST/LAST clause.
### Expected behavior
The MySQL dialect should omit writing out the NULLS LAST clause, since its
not a supported feature of the DB.
