chore(gha): fix macos action/setup-go@v4 cache miss.

Set the same Go version as specified in the `go.mod`
because of many similar issues related to the setup-go
cache unable to work when go.mod specifies a different
version.

- actions/setup-go#424

Additionally, the rand.Seed() was updated to use
rand.New(rand.NewSource(seed)) because the former was
removed from Go1.20.
