Create token example doesn't works

[victorabarros]

Hi guys!

I'm having some problem in try create token following:

• Example from https://pkg.go.dev/github.com/dgrijalva/jwt-go#example-New--Hmac

	// Create the token
	token := jwt.New(jwt.GetSigningMethod("HS256"))
	// Set some claims
	token.Claims["foo"] = "bar"
	token.Claims["exp"] = time.Now().Add(time.Hour * 72).Unix()
	// Sign and get the complete encoded token as a string
	tokenString, err := token.SignedString(mySigningKey)

• Error from https://play.golang.org/p/z4zkFDWTGQ-:

go: finding module for package github.com/dgrijalva/jwt-go
go: downloading github.com/dgrijalva/jwt-go v1.0.2
go: downloading github.com/dgrijalva/jwt-go v3.2.0+incompatible
go: found github.com/dgrijalva/jwt-go in github.com/dgrijalva/jwt-go v3.2.0+incompatible
./prog.go:12:14: invalid operation: token.Claims["foo"] (type jwt.Claims does not support indexing)

The issue #388 (comment) helps to solve, but I think would be better if the example from documentation works too.

It looks like the API changed several years ago, but none of the documentation has been updated since.

If anyone has examples for how the new API works, that's be super useful. I'm not sure if versions > 1.0.2 are considered usable though, maybe they're still experimental?
