ORC-1333: Exclude the proto files from the nohive jar

### Why are the changes needed?

We're seeing some conflicts in the proto files when updating Iceberg in Trino: trinodb/trino#15079 (comment)

I think we should exclude the proto files from the `nohive` jar.

Before the change:
```
➜  java git:(main) ✗ rm -rf core/target/
➜  java git:(main) ✗ mvn package -DskipTests
➜  java git:(main) ✗ cd core/target
➜  target git:(main) ✗ unzip orc-core-1.9.0-SNAPSHOT-nohive.jar
➜  target git:(main) find . | grep -i "google/protobuf/"
./google/protobuf/timestamp.proto
./google/protobuf/field_mask.proto
./google/protobuf/api.proto
./google/protobuf/duration.proto
./google/protobuf/struct.proto
./google/protobuf/wrappers.proto
./google/protobuf/source_context.proto
./google/protobuf/any.proto
./google/protobuf/type.proto
./google/protobuf/empty.proto
./google/protobuf/compiler
./google/protobuf/compiler/plugin.proto
./google/protobuf/descriptor.proto
```

After the change:
```
➜  java git:(main) ✗ rm -rf core/target/
➜  java git:(main) ✗ mvn package -DskipTests
➜  java git:(main) ✗ cd core/target
➜  target git:(main) ✗ unzip orc-core-1.9.0-SNAPSHOT-nohive.jar
➜  target git:(main) ✗ find . | grep -i "google/protobuf/"
∅
```

Interestingly enough, the normal jar doesn't contain these proto files:
```
➜  java git:(main) ✗ rm -rf core/target/
➜  java git:(main) ✗ mvn package -DskipTests
➜  java git:(main) ✗ cd core/target
➜  target git:(main) unzip orc-core-1.9.0-SNAPSHOT.jar| grep -i proto
➜  target git:(main) find . | grep -i "google/protobuf/"
∅
```
