chore: remove deprecated rand.Seed usage

[pujidjayanto]

Description

Fixes #1026

Since Go 1.20, the global math/rand source is automatically seeded, making explicit rand.Seed(time.Now().UnixNano()) calls unnecessary. The Go team deprecated rand.Seed in 1.20 and it's a no-op as of the latest versions.

This PR removes the redundant rand.Seed calls and their associated math/rand and time imports from:

• main.go
• suite_test.go

I only found the usage on those 2 files (exclude vendor)

Hi @pujidjayanto. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
