v2.2.1 - Whisper easier

Since the transcriber is set to "auto" to select best available of gpu or cpu acceleration. Therefore, I added 8 threads default (when using cpu) instead of 4, which is the default from faster-whisper library when not otherwise specified.

Added instructions specific to BGE embedding models, which was accidentally overlooked previously, which will greatly increase the effectiveness of these models (now rivaling or possibly exceeding the instructor embeddings models' quality).
