Transformers v5 Support

Transformers v5.0 and its required huggingface_hub versions have dropped support of requests in favor of httpx. The former was also used in sentence-transformers, but not listed explicitly as a dependency. This patch removes the use of requests in favor of httpx, although it's now optional and not automatically imported. This should also save some import time.

Importing Sentence Transformers should now not crash if requests is not installed.
