fix typo, replace kyuubiJdbcUrl with kyuubiJdbcUrlTemplate. ### _Why are the changes needed?_ fix typo, should be String.format(kyuubiJdbcUrlTemplate, ...) ### _How was this patch tested?_ just fix typo, no test need. - [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible - [ ] Add screenshots for manual tests if appropriate - [ ] [Run test](https://kyuubi.readthedocs.io/en/master/develop_tools/testing.html#running-tests) locally before make a pull request Closes #4954 from uicosp/patch-1.

Getting Started with Hive JDBC
How to get the Kyuubi JDBC driver
Kyuubi Thrift API is fully compatible w/ HiveServer2, so technically, it allows to use any Hive JDBC driver to connect Kyuubi Server. But it's recommended to use Kyuubi Hive JDBC driver, which is forked from Hive 3.1.x JDBC driver, aims to support some missing functionalities of the original Hive JDBC driver.
The driver is available from Maven Central:
<dependency>
<groupId>org.apache.kyuubi</groupId>
<artifactId>kyuubi-hive-jdbc-shaded</artifactId>
<version>1.7.0</version>
</dependency>
Connect to non-kerberized Kyuubi Server
The below java code is using a keytab file to login and connect to Kyuubi server by JDBC.
package org.apache.kyuubi.examples;
import java.sql.*;
public class KyuubiJDBC {
private static String driverName = "org.apache.kyuubi.jdbc.KyuubiHiveDriver";
private static String kyuubiJdbcUrl = "jdbc:kyuubi://localhost:10009/default;";
public static void main(String[] args) throws SQLException {
try (Connection conn = DriverManager.getConnection(kyuubiJdbcUrl)) {
try (Statement stmt = conn.createStatement()) {
try (ResultSet rs = st.executeQuery("show databases")) {
while (rs.next()) {
System.out.println(rs.getString(1));
}
}
}
}
}
}

public static void main(String[] args) throws SQLException {
String clientPrincipal = args[0]; // Kerberos principal
String clientKeytab = args[1]; // Keytab file location
String serverPrincipal = arg[2]; // Kerberos principal used by Kyuubi Server
String kyuubiJdbcUrl = String.format(kyuubiJdbcUrlTemplate, clientPrincipal, clientKeytab, serverPrincipal);
try (Connection conn = DriverManager.getConnection(kyuubiJdbcUrl)) {

try (ResultSet rs = st.executeQuery("show databases")) {
while (rs.next()) {
System.out.println(rs.getString(1));
