README curl is wrong image should be images

[felipeblassioli]

This part of README seems wrong because https://github.com/bentoml/BentoYolo/blob/main/service.py#L26-L29 uses batchable=True

Part of README.md:

CURL

curl -X 'POST' \
  'http://localhost:3000/predict' \
  -H 'accept: application/json' \
  -H 'Content-Type: multipart/form-data' \
  -F 'image=@demo-image.jpg;type=image/jpeg'
Python client

import bentoml
from pathlib import Path

with bentoml.SyncHTTPClient("http://localhost:3000") as client:
    result = client.predict(
        image=Path("demo-image.jpg"),
    )
