[CI] Increase number of go-mate test positions to 1000 Adding more positions for this CI run means failure will become less random, and allow us to spot regressions timely. I also added a deterministic single threaded run as well. Both runs now have a time out: each will fail after 30 minutes. closes https://github.com/official-stockfish/Stockfish/pull/7073 No functional change
