Based on builds results https://m2build-ur.devops.magento.com/job/All-User-Requested-Tests/22102/ failures for Static-Tests-UR and Magento-Health-Index-UR may be safely ignored.

• Health Index failure caused by Integration tests fixture, therefore may be skipped.
• Static Tests fail for files unrelated to the Inventory. Problem is caused by merged with the core mainline. May be skipped.
