SetCookie broken

[sguillia]

Hello

It seems you have made a breaking change 4 hours ago (our CI broke)

In source file, SetCookie expects 8 parameters
https://github.com/gin-gonic/gin/blob/master/context.go#L778

In the README, SetCookie expects 7 parameters
https://github.com/gin-gonic/gin/blob/master/README.md

c.SetCookie("gin_cookie", "test", 3600, "/", "localhost", false, true)

On the CI

... not enough arguments in call to c.SetCookie
	have (string, string, number, string, string, bool, bool)
	want (string, string, int, string, string, http.SameSite, bool, bool)

Could you please update the README so that it is consistent with the source code? Otherwise, it is hard to find out where the problem comes from, and which one is the good prototype :-)
