Unable to use BAAI/bge-reranker-base model for reranking

[shizidushu]

LocalAI version:
localai/localai:v2.16.0-cublas-cuda12

Environment, CPU architecture, OS, and Version:
Linux LAPTOP-LENOVO 5.15.153.1-microsoft-standard-WSL2 #1 SMP Fri Mar 29 23:14:13 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

Describe the bug
It tries to load mixedbread-ai/mxbai-rerank-base-v1 instead.

To Reproduce
Use the following yaml.

name: bge-reranker-base
backend: rerankers

parameters:
  model: cross-encoder
  pipeline_type: zh

After read https://github.com/AnswerDotAI/rerankers/blob/e53b2714a935937561c9045326ed19bfa5082129/rerankers/reranker.py#L12-L16 and

LocalAI/backend/python/rerankers/backend.py

Line 62 in ac4a94d

kwargs['lang'] = request.PipelineType

, I think set pipeline_type: zh will make BAAI/bge-reranker-base to be used. But it loads mixedbread-ai/mxbai-rerank-base-v1 instead.
