All of our calls to Seed were with current time, so they
were intended to produce different pseudo-random sequences on each run.
We were never calling Seed with a fixed value to create reproducible
sequences of pseudo-random numbers.  Therefore it should be safe to just
delete the calls.

per the docs (https://pkg.go.dev/math/rand@master#Seed):

> If Seed is not called, the generator is seeded randomly at program startup.

> Prior to Go 1.20, the generator was seeded like Seed(1) at program startup. To force the old behavior, call Seed(1) at program startup. Alternately, set GODEBUG=randautoseed=0 in the environment before making any calls to functions in this package.

> 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.
