fix: expand model if depth <= defaultModelExpandDepth

[twjasa]

Description

The prop expanded is now expanded if it's less or equal than defaultModelExpandDepth

Motivation and Context

An issue was open (#8008) indicating that the prop defaultModelExpandDepth did not had the correct behavior.

How Has This Been Tested?

Create a new test.yaml file inside ./dev-helpers/ and paste the yaml code that is in the issue link. (#7549)
In ./dev-helpers/index.html change url parameter of ui variable to: ./dev-helpers/test.yaml
run npm run dev in terminal
Open http://localhost:3200/
Check if depth level expand properly depending on defaultModelExpandDepth
