chore: instance rand.Seed to rand.Source (#1233)

The `rand.Seed` method is currently deprecated, use rand Replace with
the `NewSource` method.

```
// Deprecated: As of Go 1.20 there is no reason to call Seed with
// a random value. Programs that call Seed with a known value to get
// a specific sequence of results should use New(NewSource(seed)) to
// obtain a local random generator.
```
