Dont run exhaustive tests on *EVERY* commmit in a branch (#18817) (#18820)

In the case a new branch is pushed to the elastic/logstash repo exhaustive tests
are run. This happens for example when updatecli or other GHA orchestrated updates
occur for automating version bumps etc. Previously *EVERY* commit in that branch had
the full exhaustive test run against it. We only want one commit, therefore we configure
it to cancel intermediate commits. This drastically saves testing resources.
