`c.SetCookie` function is missing expire field

[jsjain]

Description

Currently c.SetCookie does not accept cookie Expire field which is present in http.Cookie struct and might be important if you want to maintain short lived sessions via cookie method.

I am aware that we can set cookie via-

	http.SetCookie(c.Writer, &http.Cookie{
		Name:     "session",
		Value:    "some-session-value",
		Domain:   "localhost",
		Expires:  "Expiry time", <- this is missing
		Secure:   false,
		HttpOnly: false,
	})

But since we are already exposing a helper function to set cookie, i suppose extending it to support expire would be helpful for others.

How to reproduce

c.SetCookie("session", "some-session-value", 0, "/", "localhost", false, false)

Expectations

c.SetCookie("session", "some-session-value", 0, "/", "localhost", false, false, timeToExpire) <- adding additional param for time to expire

I can raise the PR for the same sine this is fairly small change and would love to contribute to this project.

Environment

• go version: 1.18.5
• gin version (or commit ref): v1.8.1
• operating system: Platform Agnostic

I believe what you need is available via maxAge param in the SetCookie method. func (c *Context) SetCookie(name, value string, maxAge int, path, domain string, secure, httpOnly bool) source

got it, after some further reading got to know that expires is now deprated and max-age takes priority in case both are set. SO answer
