[distribution] remove pulsar-io-debezium nar package (#3656)

*Motivation*

Fixes #3651

`pulsar-io-debezium` is a normal module but not a connector package.
it was added as a connector package by mistake at #3601. This would
cause failing to load connectors during broker starts up.

*Changes*

- remove nar plugin from `pulsar-io-debezium`
- remove `pulsar-io-debezium` from distribution
- add `pulsar-io-kafka-connect-adaptor` in the website
