Description

Hi,

Again, thanks for your amazing work for Bertopic. I used Bertopic for many research projects.

I recently noticed that there may be a tricky bug for vectorizer_model. I checked the code, I found when I pass a cutomised vectorizer_model into BerTopic, the n_gram_range defined in BerTopic class will not be passed to it. Instead, we need to pass both arguments to the vectorizer_model when the vectorizer_model creats.

Research direction

Start by tracing how BerTopic creates or accepts a custom vectorizer_model and where n_gram_range is handled. Reproduce the behavior with a custom vectorizer and compare it with the default path. Done means the configured n_gram_range is consistently honored for custom vectorizers, with coverage for that case.
