fix: git auto generate header issue fixed (#33016)

## Description
The autoGeneratedHeaders property in actionConfiguration is
unnecessarily getting introduced as git changes. This PR fixes that
issue.

With current implementation, In a git connected application, when we
create any action and bind it to table widget, once we successfully
commit these changes, after surfing the application without making any
changes, we can see new changes to be committed for git and in those
changes we can see `autoGeneratedHeaders: []` inside
actionConfiguration. This issue has been fixed by initialising the field
by default when we create action.
