[FlightSQL] GetCatalogsBuilder does not sort the catalog names

[niebayes]

The GetCatalogsBuilder does not apply sorting as specified in the documentation comments. In contrast, other builders, such as GetDbSchemasBuilder and GetTablesBuilder, sort the record batch exactly as described in their documentation.

See:

arrow-rs/arrow-flight/src/sql/arrow.flight.protocol.sql.rs

Lines 120 to 122 in e1e8814

	/// The returned data should be ordered by catalog_name.
	#[derive(Clone, Copy, PartialEq, ::prost::Message)]
	pub struct CommandGetCatalogs {}

And see:

arrow-rs/arrow-flight/src/sql/metadata/catalogs.rs

Lines 70 to 79 in e1e8814

	pub fn build(self) -> Result<RecordBatch> {
	let Self { catalogs } = self;
	let batch = RecordBatch::try_new(
	Arc::clone(&GET_CATALOG_SCHEMA),
	vec![Arc::new(StringArray::from_iter_values(catalogs)) as _],
	)?;
	Ok(batch)
	}
