feature: Add Hugging Face embedding provider

[bwook00]

Did you check the docs?

• I have read all the NeMo-Guardrails docs

Is your feature request related to a problem? Please describe.

I want to use Hugging Face embedding model like bge, e5 etc ...
I checked the docs, but it doesn't support yet.

If there was a provider to make it easy to use the embedding model in HuggingFace, more people would feel comfortable using it.

I'd like to work on this issue, so if you don't mind, set me up as an Assignee!, or comment! 🤗

Describe the solution you'd like

I saw your PR #702. So I'm planning to do something similar to this.

Describe alternatives you've considered

I checked the nemoguardrails.llm.providers.HuggingFacePipelineCompatible, but I think this is only for LLMs
