fix: Always get the same value where you want to get it at random.

phone.go:70:47: SA4030: (*math/rand.Rand).Intn(n) generates a random value 0 <= x < n; that is, the generated values don't include n; rand.Intn(1) therefore always returns 0 (staticcheck)
	return fmt.Sprintf("(%s) %s", boxDigitsStart[rand.Intn(1)], out)
	                                             ^
phone.go:94:45: SA4030: (*math/rand.Rand).Intn(n) generates a random value 0 <= x < n; that is, the generated values don't include n; rand.Intn(1) therefore always returns 0 (staticcheck)
	return fmt.Sprintf("+%s%s", boxDigitsStart[rand.Intn(1)], strings.Join(slice.IntToString(ints), ""))
	                                           ^

Hi @soranoba

Can you re-fixing this again, I just fixing some linter issue in #167

[soranoba]

rand.Intn(1) always returns 0.
So, boxDigitsStart[rand.Intn(1)] always is "777".

This fix is to correctly return random values.
