[Fix] GPT plugin: explicitly set POST method for API requests

Fixes #5859

Some API providers (like Ollama) strictly require POST method on their
endpoints and return 405 Method Not Allowed for GET requests. While
rspamd_http auto-detects POST when a body is present, explicitly setting
the method ensures correct behavior in all cases.
