IsAny() multi error support

[nikitacrit]

Hello! At the moment the following code will produce the result "no". I suggest a fix based on the code found in the original method Is().

func main() {
	err := errors.Join(io.EOF, errors.New("gopher"))

	if errors.IsAny(err, io.EOF, net.ErrClosed) {
		fmt.Print("yes")
	} else {
		fmt.Print("no")
	}
}
