How to properly initialize a random number generator in Go?

Hi! I'm new to Go and trying to figure out random number generation. I read that Go has the `math/rand` package, but I have a problem: every time I run the program, I get the same sequence of numbers. Here's my code: ```go package main import ( "fmt" "math/rand" ) func main() { for i := 0; i < 5; i++ { fmt.Println(rand.Intn(100)) } } ``` Every run, the output is always the same: `81, 87, 47, 59, 81`. I expected the numbers to change. I've heard that I need to somehow "seed" the generator, but I don't understand how to do it correctly. When I try to use `rand.Seed(time.Now().UnixNano())`, I get a linter warning that Seed is deprecated in Go 1.20. How do I properly initialize the generator?
