Spring-ai Embedding clients in different maven modules share the same package name, this needs to change

For example, the module spring-ai-postgresml-embedding-client has the class PostgresMEmbeddingClient in the package org.springframework.ai.embedding and transformers-embedding module has TransformersEmbeddingClient in the same package org.springframework.ai.embedding

When making this change, create a more specific name for the transformers-embedding perhaps onnx-embedding-client?

Also, there is a convention of having the artifact contain the prefix spring-ai. The Postgres embedding clients doesn't follow this convention.
