Description

When adding a value to NormalizeSchemas of AvroSerializerConfig, the AvroSerializer fails with AvroSerializer: unknown configuration property avro.serializer.normalize.schemas even it uses it after the validation

How to reproduce

Set a true value to an AvroSerializerConfig and then use it for create a specific AvroSerializer
`
var schemaRegistryConfig = new SchemaRegistryConfig
{
Url = "schemaRegistryUrl",
};

var avroSerializerConfig = new AvroSerializerConfig
{
// optional Avro serializer properties:
BufferBytes = 1024,
AutoRegisterSchemas = false,
SubjectNameStrategy= SubjectNameStrategy.Record,
NormalizeSchemas = true,
};
var avroSerializer = new AvroSerializer(schemaRegistry, avroSerializerConfig);
`
