Regression Testing CI failing #620
Description
-
The python version it's trying to use are outdated. See https://github.com/QuantConnect/lean-cli/actions/workflows/regression-testing.yml
-
To the cron job type of run we should add running the CI on PRs and master merge, like the rest of the tests, so failures are not missed
-
Generically we could move python and OS versions into an external centralized file under test folder and reuse them in the different CIs
