[Improve][Connectors-V2] Improve NoPrivilegeException for Paimon

[hawk9821]

Purpose of this pull request

Paimon's NoPrivilegeException can be divided into two situations:

1. The first is when the username or password are incorrect
2. The second one is unauthorized access

The first situation is converted to CatalogException(User %s not found, or password incorrect.) , and the second situation is converted to PaimonConnectorException(PaimonConnectorErrorCode.NO_PRIVILEGE) , Convert Paimon's exception to Seattunnel's exception.

Does this PR introduce any user-facing change?
