FIX: api key header error

[devhaozi]

According to the documentation of huggingface: By default the server responds to every request. With an api key set, the requests must have the Authorization header set with the api key as Bearer token., the use of API_KEY in the plugin is incorrect, and should use Bearer Token.

Our implementation predates TEI support for API keys by a couple months, so we relied on a reverse proxy doing API Key header verification that uses this signature, meaning we can't simply merge this.

If so, what do you think about adding both the X-API-KEY and Authorization headers?

@xfalcox fixed, PTAL.
