fix: update HuggingFaceEmbeddingEncoder to use `langchain_huggingface` instead of `langchain-community` (#3436)
Similar to https://github.com/Unstructured-IO/unstructured/pull/3433.
### Summary
This PR aims to update `HuggingFaceEmbeddingEncoder` to use
`HuggingFaceEmbeddings` from `langchain_huggingface` package instead of
the deprecated version from `langchain-community`. This resolves the
deprecation warning and ensures compatibility with future versions of
langchain.
### Testing
```
from unstructured.documents.elements import Text
from unstructured.embed.huggingface import HuggingFaceEmbeddingConfig, HuggingFaceEmbeddingEncoder
embedding_encoder = HuggingFaceEmbeddingEncoder(
config=HuggingFaceEmbeddingConfig()
)
elements = embedding_encoder.embed_documents(
elements=[Text("This is sentence 1"), Text("This is sentence 2")],
)
query = "This is the query"
query_embedding = embedding_encoder.embed_query(query=query)
[print(e.embeddings, e) for e in elements]
print(query_embedding, query)
print(embedding_encoder.is_unit_vector(), embedding_encoder.num_of_dimensions())
```
**Expected behavior**
No deprecation warning should be displayed. The code should use the
updated `HuggingFaceEmbeddings` class from the `langchain_huggingface`
package.
