docs(context): #3369 modify the annotation about Context.Param()

[Cookiery]

If you don't want to motify the annotation. Maybe I can fix it in the tree.go (func Get or func ByName).

Please feel free to reach out with any questions.

Thank you very much.

This change is wrong in v1.9.1.
The return of c.Param doesn't contain slash.

Any update on this @Cookiery? I am on v1.9.1 and c.Param doesn't contain a slash

router.GET("/user/:id", func(c *gin.Context) {
    // a GET request to /user/john
    id := c.Param("id") // id == "john"
    // a GET request to /user/john/
    id := c.Param("id") // id == "john"
})

// Param returns the value of the URL param.
// It is a shortcut for c.Params.ByName(key)
//
//	router.GET("/user/:id", func(c *gin.Context) {
//	    // a GET request to /user/john
//	    id := c.Param("id") // id == "john"
//	    // a GET request to /user/john/
//	    id := c.Param("id") // id == "/john/"
//	})
