[BUG] Claude V3 blueprint needs to pass over system prompt

[mingshl]

What is the bug?
A clear and concise description of the bug.
In the current claude v3 blueprint, it does not include the system field in the response_body in the connector, thus the system prompt cannot be pass to the model or it will only use the default prompt and cannot be modify for specific use case.

The change needs to be similar to the following

Europa's icy surface likely hides an ocean of liquid water beneath. Ganymede is the largest moon in the Solar System. Callisto is also thought to harbor a subsurface ocean. Many of Jupiter's other moons are much smaller and more irregularly shaped. Several were discovered during the past few decades using ground- and space-based telescopes."
