Nit: improve route not supported error message #80
Description
Currently when a path doesn't match, we just return [BricksLLM] route not supported, which makes it slightly tricky to debug API calls made via an SDK, cause the SDK hide the request path from the user.
Maybe would be nice if we also return the request path along with the error, cause sometimes the error is really obvious.
Something like [BricksLLM] "/api/providers/foo/bar" is not a supported route?
