[Bug] error in initSerDe: java.lang.ClassNotFoundException Class org.apache.paimon.hive.PaimonSerDe not found

### Search before asking

- [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.

### Paimon version

paimon-1.0

### Compute Engine

spark-3.2

### Minimal reproduce step

Use SparkSQL Engine、Hive metastore

1. Create table in hive metastore.（use create table statement）
2. Delete the HDFS directory of the table.(hdfs dfs -rm -r table dir)
3. Failed to delete table.（use drop table statement）.

### What doesn't meet your expectations?

Tables stored in HMS cannot be deleted using delete statements.

### Anything else?

Some users may delete the table directory directly during use. In this case, the table information in HMS cannot be cleared.

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start by reproducing the initSerDe ClassNotFoundException with Spark 3.2, Paimon 1.0, SparkSQL, and a Hive metastore after deleting the table's HDFS directory. Trace the drop-table path and verify that the Hive metastore entry is cleared successfully even when the directory is missing.
