Only test newly added Fleet-maintained apps in pull requests #35887
Description
Problem
Currently when you add a new Fleet-maintained app (FMA) pull request, a check is run that tests all FMAs, including the new one(s) being submitted. We are currently at 70 apps which means these checks can take upwards of 40 minutes. This will only get longer the more apps we add.
We also run into an issue from time to time where unrelated FMAs will fail within these checks due to URLs being out of date. This blocks us merging the new FMA confidently because we want to see all checks passing.
What have you tried?
N/A
Potential solutions
Create new workflows that only work on PRs that detect what FMAs are new and only validates those, leaving the older, already tested FMAs unchecked in the pull request.
What is the expected workflow as a result of your proposal?
New FMA pull requests will be much quicker and not present false positives.
