Replace deprecated `math/rand` functions (#30733)v1.23.0-dev

Suggested by logs in #30729

- Remove `math/rand.Seed`
`rand.Seed is deprecated: As of Go 1.20 there is no reason to call Seed
with a random value.`
- Replace `math/rand.Read`
`rand.Read is deprecated: For almost all use cases, [crypto/rand.Read]
is more appropriate.`
- Replace `math/rand` with `math/rand/v2`, which is available since Go
1.22
