chore: skip pytest+CI+IAST test (#15001)

## Description

Can we skip these?

> yes, for sure, those tests are related to pytest + iast (AKA IAST in
the CI) and it was a innovation week project, it's not a "real" feature
yet

## Testing

<!-- Describe your testing strategy or note what tests are included -->

## Risks

<!-- Note any risks associated with this change, or "None" if no risks
-->

## Additional Notes

<!-- Any other information that would be helpful for reviewers -->
