[Integration][ADO] Fix Entity Update Issue on Master Default Branch

[lordsarcastic]

Description

What - Fixed a bug where push events aren't processed on default branches

Why - Push events are only processed on configured branches from port app config which makes things inflexible and causes bugs for other customers

How - Check for default branch in payload and run push events if current branch is default branch.
