## Changes
The comment block appears on all PRs, even if the integration tests are
automatically triggered. This is quite noisy. This change limits those
comments to PRs from forks.
## Tests
Have to try by merging...
## Changes
The existing workflow already had 2 trigger conditions, so instead of
adding a third (and seeing more "skipped" jobs), I split them up into
dedicated workflow files, each with their own trigger condition.
The integration test status is reported back via commit status.
## Tests
We can confirm that everything works as expected as this PR moves from
here to the merge group to main.
