vercel ai sdk generateText warns cause system messages are contained in messages array

[8de2fdb0]

Currently there is a warning from coming from callse vercel ai's generateText function.

AI SDK Warning: System messages in the prompt or messages fields can be a security risk because they may enable prompt injection attacks. Use the system option instead when possible. Set allowSystemInMessages to true to suppress this warning, or false to throw an error.

System prompt messages should be moved to the system parameter of generateText.

Looks like it was added recently and will be rejected in the next mayor (6.x to 7.x)
