Convert gocardless/draupnir to GitHub Actions (#490)

* Add workflow gocardless/draupnir/build-integration

* chore: polishing valet ci output

* Pin ubuntu version to 22.04

Remove commented out build-production, it's only used once, no point in
uploading and downloading the artifact for it

* Remove circleci directory

* Improve triggers and cancel running jobs
