Subject: [PATCH 1/3] [devops] Make the API diff pipeline use a pr: trigger.

Unfortunately Azure DevOps doesn't properly report GitHub checks for pipelines
triggered by another pipeline, when that other pipeline was triggered from a
pr trigger.

So go back to triggering the API diff pipeline using a pr: trigger.

This effectively reverts #21880 ("[CI] Make the API diff be triggered as soon as the config of the build is done.")
