How Has This Been Tested?

I have added unit test for HuggingFaceEmbedder. (first unit test for an embedder 🎉)

Also tested using,
main.py -

import os
from embedchain import App

app = App.from_config(config_path="./config.yaml")

app.add("https://en.wikipedia.org/wiki/Sun_Tzu")

while True:
    question = input("Enter question: ")
    if question in ["q", "exit", "quit"]:
        break
    answer = app.query(question)
    print(answer)

config.yaml -

llm:
  provider: openai
  config:
    model: 'gpt-3.5-turbo'
    temperature: 0.5
    max_tokens: 1000
    top_p: 1
    stream: false

embedder:
  provider: huggingface
  config:
    model: 'nomic-ai/nomic-embed-text-v1'
    model_kwargs:
      trust_remote_code: True

Output -

Enter question: which book did sun tuz write?
Sun Tzu is traditionally credited as the author of The Art of War, an influential work of military strategy that has affected both Western and East Asian philosophy and military thought.
