Describe the bug
When attempting to run the pulsar lakehouse sink example(! https://streamnative.io/blog/announcing-delta-lake-sink-connector-apache-pulsar ) locally, an java error occurs:

ERROR org.apache.pulsar.functions.LocalRunner - Encountered error starting localrunner
java.lang.IllegalArgumentException: Could not validate sink config: Cannot construct instance of org.apache.pulsar.ecosystem.io.lakehouse.SinkConnectorConfig (no Creators, like default constructor, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information

To Reproduce
After init of the pulsar standalone cluster: run the commands in https://streamnative.io/blog/announcing-delta-lake-sink-connector-apache-pulsar

Actual command:
PULSAR_HOME/bin/pulsar-admin sinks localrun --sink-config-file /tmp/pulsar-functions/connectors/pulsar-delta-lake-sink-config.json

with the settings from the example: with my local cluster settings updated over where needed (tenant / namespace)

Expected behavior
To have the sink create succesfully
