[BUG] DatabricksArray.getBaseTypeName() returns incorrect type #1738

Describe the bug
DatabricksArray.getBaseTypeName() returns the type name of the full array, not the type name of its elements. DatabricksArray.getBaseType() always returns Types.OTHER.

The java.sql.Array docs say that both methods should describe the elements of the array.

To Reproduce

Properties props = new Properties();
props.setProperty("...", "...");
props.setProperty("EnableComplexDatatypeSupport", "1");

try (Connection con = DriverManager.getConnection("jdbc:databricks://<host>:443/", props);
    Statement stmt = con.createStatement();
    ResultSet rs = stmt.executeQuery("SELECT ARRAY(ARRAY(1, 2, 3))")) {
    rs.next();
    Array outer = rs.getArray(1);
    Array inner = (Array) ((Object[]) outer.getArray())[0];
    System.out.println(outer.getBaseTypeName() + " " + outer.getBaseType());
    System.out.println(inner.getBaseTypeName() + " " + inner.getBaseType());
}

Actual output:

ARRAY<ARRAY<INT>> 1111
ARRAY<INT> 1111

Expected behavior

ARRAY<INT> 2003
INT 4

getBaseTypeName() returns the element type name and getBaseType() returns the java.sql.Types code of the element type.
