Incompatibility of the plugin with kafka-connect

Hey, everybody!

I have this situation:

I was using image `confluentinc/cp-kafka-connect:7.7.0` in conjunction with clickhouse-kafka-connect v.1.2.0 and everything worked fine.

After a certain period of time I updated image `confluentinc/cp-kafka-connect` to version 7.7.1. And everything stopped working, an error appeared:
```

I have this setting in docker-copmpose:

```

```
I put the clickhouse-kafka-connect plugin in the `/usr/share/confluent-hub-components` folder. I don't add anything else. All other packages like `com.google.java-protobuf` etc. - come by default in the image (at least I see jar files with those names). I can also run the clickhouse-kafka-connect connector itself and it runs on version 7.7.0 and 7.7.1.

But when I post a message to a topic and kafka-connect starts pulling the message and apparently deserializing it, an error occurs.

By the way, I have the same settings as for `confluentinc/cp-kafka-connect:7.7.0`. But as soon as I change the image version from 7.7.0 to 7.7.1 - the error occurs.

A little searching for a solution - there was a suggestion that it is connected with some incompatibility of package versions, but I can't say for sure.
Can you tell me if someone has encountered this problem and knows how to solve it?
Or maybe someone has some ideas what can be tried to solve the problem.
I will be very grateful.

Reproduce the failure with confluentinc/cp-kafka-connect:7.7.0 and 7.7.1, the clickhouse-kafka-connect plugin, and the provided Docker Compose settings. Start at ProtobufConverter.toConnectData in the stack trace and compare the bundled protobuf and Schema Registry dependencies; done means identifying the incompatible package or version and documenting a verified resolution.
