chore: check slice.Contains in for range block

[eval-exec]

faker/support/slice/helpers.go

Lines 7 to 16 in 7460bf3

	// Contains Check item in slice string type
	func Contains(slice []string, item string) bool {
	set := make(map[string]struct{}, len(slice))
	for _, s := range slice {
	set[s] = struct{}{}
	}
	_, ok := set[item]
	return ok
	}

we don't need to make a map to check a slice contain a string, just do it in for range
