embeddings dependency

[arendjr]

I discovered a dependency on the embeddings crate, which seems to be an empty placeholder: https://github.com/getgrit/gritql/blob/main/crates/core/Cargo.toml#L17

Is this something that is still supposed to be initialized, or something that should be cleaned up?

It's a placeholder for some internal experiments we’re running for retrieving from an embedding database. We have a few similar crates, but they're all optional dependencies.
