Possible need to properly seed in a deterministic order for benchutils

[shahzadlone]

The following seeding code was removed in #1689,
Due to https://stackoverflow.com/questions/75597325/rand-seedseed-is-deprecated-how-to-use-newrandnewseed,
In tests/bench/bench_util.go,

	// create a consistent seed value for the random package
	// so we don't have random fluctuations between runs
	// (specifically thinking about the fixture generation stuff)
	seed := hashToInt64("https://xkcd.com/221/")
	rand.Seed(seed)

Discussion: #1689 (comment)

Making issue for traceability incase we want to have determinism again.
