version conflict： the doc of experiments-nfcorpus.md

It says that

python -m pyserini.encode \
  input   --corpus collections/nfcorpus/corpus.jsonl \
          --fields title text \
  output  --embeddings indexes/nfcorpus.bge-base-en-v1.5 \
          --to-faiss \
  encoder --encoder BAAI/bge-base-en-v1.5 **--l2-norm** \
          --device cpu \
          --pooling mean \
          --fields title text \
          --batch 32

python -m pyserini.encode \
  input   --corpus collections/nfcorpus/corpus.jsonl \
          --fields title text \
  output  --embeddings indexes/nfcorpus.bge-base-en-v1.5 \
          --to-faiss \
  encoder --encoder BAAI/bge-base-en-v1.5 --l2-norm \
          --device cpu \
          --pooling mean \
          --fields title text \
          --batch 32

but in the latest version, it could find --l2-norm --pooling mean

I think the maintainers maybe forget the issue
