Issue:
The 'alluxio.hadoop.security.kerberos.keytab.login.autorenewal' configuration is wrong in the HDFS docs
**Page**
https://docs.alluxio.io/os/user/stable/en/ufs/HDFS.html

**Summary**
https://github.com/Alluxio/alluxio/blob/9ef7552d345fc08f96ce9041d98ddf17e73b907d/docs/en/ufs/HDFS.md?plain=1#L145
There is a bug here, because the code is using 'alluxio.hadoop.kerberos.keytab.login.autorenewal', so the user configuration 'alluxio.hadoop.security.kerberos.keytab.login.autorenewal' does not work.


```java
    public static final String HADOOP_KERBEROS_KEYTAB_LOGIN_AUTORENEWAL =
        "alluxio.hadoop.kerberos.keytab.login.autorenewal";
```
https://github.com/Alluxio/alluxio/blob/main/dora/core/common/src/main/java/alluxio/conf/PropertyKey.java#L8687-L8688

Therefore, the documentation should be modified to 'alluxio.hadoop.kerberos.keytab.login.autorenewal=true'.

 A known limitation is that the Kerberos TGT may expire after
 the max renewal lifetime. You can work around this by renewing the TGT periodically. Otherwise you

 The user can also use `alluxio.hadoop.security.krb5.conf` to specify the krb5.conf file location
