Refactor random number generation and add version-specific implementations
Removed error handling from `randNum` in `random_test.go` and introduced new `randNum` implementations for different Go versions (1.19, 1.20-1.21, 1.22+). This ensures compatibility with different versions of Go and utilizes the appropriate version-specific random number generation methods. We are using math/rand instead crypto/rand. For our needs this should be sufficient.
