Merge bitcoin#25440: log: Use consistent wording in random.cpp log

c01ae8f Use consistent wording in log (Igor Bubelov)

Pull request description:

  It's a trivial change, but it bothers me a bit that two log lines in a row aren't grammatically identical while following exactly the same pattern. I've read `contributing.md` and I'm aware that changes like this are usually being ignored and dropped, but I decided to leave it here anyway in case someone feels the same way about inconsistent log messages or grammar =)
