Issue

Not actually a bug, just a missing userInfo typing for generateCsrf decorator function. Now function parameters accept only fastifyCsrfProtection.CookieSerializeOptions, but userInfo should also be possible to pass

I did not investigate now if this is a valid claim. But if you are willing to provide a PR with tests and typings, I can promise you that we can evaluate it and merge it in a timely manner.

I confirm that this is true. The typing is indeed missing or broken. When I pass the userInfo to the reply.generateCsrf({ userInfo } as unknown as CookieSerializeOptions), the plugin works as expected. In the documentation, it is mentioned to pass the userInfo argument in a specific case. While fixing the typing, might as well add an example to the documentation to be more clear.
