Is your feature request related to a problem? Please describe.
The current implementation of TransformerSimilarityRanker only supports cross-encoder models, which limits the use of bi-encoder models like ColBERT v2.0.

Related discussion: Colbert as reranker

Describe the solution you'd like
Update the TransformerSimilarityRanker or creating a new component to support bi-encoder models like ColBERT.

Describe alternatives you've considered
Leave the current implementation as is.
