WithBaseURL should include Path

[BimDav]

Describe the bug
At the moment WithBaseURL only includes the Host part of the URL, so that giving it this kind of URL: https://api-inference.huggingface.co/v1 is not possible as it will remove the /v1 part.

To Reproduce
Use a URL with non empty Path in WithBaseURL

Expected behavior
The base URL for calls in this case should be https://api-inference.huggingface.co/v1, not https://api-inference.huggingface.co

Additional context
This enables compatibility for example with HuggingFace https://huggingface.co/docs/api-inference/tasks/image-text-to-text?code=python (openAI example at the bottom), but also probably with plenty of APIs that use this kind of versioning.

Just add / to suffix
in your case; it exactly is https://api-inference.huggingface.co/v1/
And it should work because I've got the same issue
