Prevent unintended Azure pipeline runs

By default, if an Azure pipeline does not define a `pr` attribute, Azure
takes the default behavior of running the pipeline for *every* pull
request.

Similarly, if the `trigger` attribute is not defined, the pipeline runs
for push commits on *every* branch in the repo.

It is possible to change this default behavior on the Azure side:
https://learn.microsoft.com/en-us/azure/devops/release-notes/2023/sprint-227-update#prevent-unintended-pipeline-runs

However, since these pipelines are only ever meant to be executed on
specific events, we can change the default behavior by setting the `pr`
and the `trigger` attributes to `none` where they weren't previously
defined.
