Tests

Github actions will run a set of jobs against your PR that will lint and unit test your changes. Keep an eye out for the results from these on the latest commit you submitted. For more information, please see our testing documentation.

In order to run the advanced pipeline tests (executing a set of mock pipelines), it requires an admin to post run tests on this PR.
If you are not an admin, please ask for one's attention in #infrastructure on Slack or ping one here.
To run full set of tests, use "run tests"; a subset of tests on specific jdk version, use "run tests quick 11,20"

LGTM, and noting that with the changes in #719 and as per the PMC call this week we could have a trigger that runs when new _adopt tags are created in the repository instead of having it regularly scheduled.
