Removing try/except block in the transformers converter file during import

I would like to make a small change to L15 in the transformer converter.

Running ct2-transformers-converter command after installing Ctranslate2 throws no meaningful Exception in case a user forgets to install huggingface_hub, torch, and transformers libraries.

I had to dig deep into the code to learn why the command was not working for me. This is time-consuming for any developer.

Therefore, would the community welcome removing the try/except block here, so that python could throw a ModuleNotFoundError instead?
